Unethical Actions and Crimes (especially some 'spy' ones)

Terrorism

Bombs/Nukes.

The Status Quo.

Sabotage

Extortion

Spying, Stalking and Harassment

Infiltration (and associated crimes, like poisoning and making the secretary sick to take her place)

The Motherfucking Greater Good.

Refusing to understand a fucking 'NO'.

Reading other people mails, cellphone and stuff. Or restraining them.

Unethical information gathering. Leaking the information for the wrong person.

Use other people as bait/decoy/scapegoat/cover/distraction.

Drugging (potions too). Also, don't mess with people's food. Never.

Doing anything to a person in vulnerable state, like unconcious, sleeping or injured.

Bugs, Trackers and Cameras. (Non-consensual pictures and videos)

Steal Information/Documents

Blackmail and Bribe

Unethical and Ilegal Interrogation

Take blood/DNA without consent. Stealing a blood/DNA sample or a blood test too.

Corporal Punishment, Violence, Multilation, Torture, Physical Abuse…

Professional Impersonificators (Like Doctors Theraphists, Drivers, Police, Babysitters). Infiltration (as a Maid? Secretary? Fake Friend? Teacher?) or just having those people in your pocket.

A bad solution to a real problem.

Propriety

Steal MacGuffin, Objects in General or 'Confiscation' or Modification of said McGuffin (because of curiousity, greed, you want to taunt someone)

Steal inventions, discoveries or just take the credit. Etnopiratary.

Grave Robbing or any disrespect to an corpse.

Hoard of Knowledge, Resources, Lands...

Money is a great source of crazy ass conflicts (Heritage? Lottery? Marriage's finances?)

Stealing Inheritance. Stealing things like work and art. Doing it 'legaly' is even worse. Attempt/Demand to get an person to 'hand over' an artefact. Refusal to give something back too.

Entitlement (some people think everything and everyone is God's gift for them or that other people legally getting something you wanted is 'stealing', may have fantasy prejudice involved).

Resources in general, from either animals or people or others ('magicals' or not).

You 'don't want it to fall in wrong hands'? Okay, pal, what are 'good hands' then? Yours?

Using an object the wrong way or something like that, dunno, just remembered Kim Kardashian with Marilyn's dress and MJ's jacket, THAT was a evil greedy villain worthy action

Threats (Do it or Else)

Threatening someone loved ones (they can be under your power in some way?) or using them against said person in any way (taking them to a dangerous place or situation? Put a bomb or something similar on them?) Trying to get said loved one under your control (like taking them to 'safety').

Threat of imprisonment. Taking a person to make their loved ones 'cooperate'. (Like a 'invitation' for a meeting or interrogation). Put them in any danger.

Threat of withhold the cure or medication for a sick person/people, can be secretely making the patient's condition worse. Offten have a relative of said patient working/helping you.

Any threat really, can be a sniper, a bomb, physical. Take advantage of a person's dependency on another.

Doing something bad to a person under your custody because they are dependent of you or you think you 'own' them, therefore have the 'right' to do so.

Any threat to free will or control (over a person self and their abilities): mindcontrol, brainwashing, potions, drugs, magical contracts and oaths, binding and seals, devices, the Cage Bird Seal from Naruto...

A unfair deal/exchange/blackmail to get incentive someone to help you/give you/stop doing something in some way. Like 'I will give the thing I stole back if you do this for me', 'I will break the deal if you steal this for me' or even 'I will heal your friend if you give me this thing', Maybe by making the person need you in first place?

Manipulation

Forced Recruitment, Servitude or Help.

Manipulation (to fight? To steal? Forcing you to do something? Fake information? Using people how? Sign you up for something without consent? Tricking you to agree to a unfair deal? Social or Emotional? Guilty Trip? Humiliation? Isolation?)

"Tests" are very manipulative, often forcing a person hand, like the Poison and Cure Gambit. Control Freaks. Attempts to exercise authority (and begin respected and obeyed as such) everywhere. Attempt to coerce, press and trap you on obeying them, giving people orders and deciding/dictating their life choices.

Use a person to/for: find another? find a place? get a object? get inside a place?

Use a Relationship as means of control and manipulation.

Forcing them to fight against their will: maybe locking they up with the opponent or left you with them? Bring the enemies to you? Put their loved one in danger? Create the problem for them to solve? Forced enlistment?

Mindfuckery, just reading (or attempting) people's mind without consent, it does not matter if you are 'curious' or how 'rightful' you are. Also erasing things too (events? information? people? alter memories?), forcing someone into another identity or to obey you, getting information.

Unfair Deals or trying to make a 'generous offer' to get something from a person (when you need or want her/him), forcing her to accept your terms, especially when the person owns you nothing. Sadistic Choices too.

Blackmail someone with arrest and prision to make them do something.

Any extreme thing to get what you want: want a person to move? Steal all their things and put in another house or burn down their house. Want a person to attend a college not other? Sabotage or sign off them. Or got them in trouble. Want them to wear some clothes not another? Burn the other clothes. Refuse to go? Send their men to 'fetch' you. Refuse to give/borrow something? Steal it.

Science and Biology

Bloodpurism. I hate it but love its plots, from both Asoiaf and Harry Potter.

Non-Consensual Experiments in General (not just the 'mad scientist' type, any non-consensual medical test, unaware ones, sterilization, fucking lobotomy and shock theraphy). Kidnapping is not really necessary, plenty of times the hospitals did more experiments than what was consented, or told the patients they were doing another thing, more vulnerable people like mentally disabled, soldiers and isolated tribes (or the non-educated poor) are easier to trick.

Using the Results of an Unethical Experiments (like the Nazis or Henrietta Lacks). Using an artefact or something similar that had unethical origins too (kinda like the philosophical stone with the Ishvalan souls)

Disrespect to Body Autonomy and personal choices. (Deny acess to things like contraceptives, pain killers and insulin, hysterectomy, tampering with it too. Information about your own body, about an medical process, breach of privacy, chastity belt, lack of medical consent, body modification or mutilation)

Anything related to hurting an animal (magical one included, any curious attempts to 'capture' one to study is also included, or entertainment). Fuck zoos by the way. Be it a 'cursed' or 'blessed' creature leave them in fucking peace.

Any breeding programs, genetic aprimorament and asthetic alterations too. Eugenics. Also if they produce or have something you want as a product or another reason (pearls, skin, venon, medicine...)

Reproduction Control and Breeding Programs, especially in minories (the Church used to kidnap and fake the death of babies of single mothers and pagans to give them to 'proper Christian couples', lesbian faced problems to their rights for insemination and adoption, mixed children were aborted without the mother's consent or even knowledge, 'pure' aryan women were 'encouraged' to join brothels to breed in Nazi Germany.) Its a fucking mess, but normal in matters of prejudice.

Kidnapping/Restriction of Freedom

The 'Rebel = Evil' mentality.

Unjust Imprisonment, Unlawfull Arrests. Double Standarts and Inequal Rights.

Kidnapping (can be complex ones like showing up at school/work or using an trap like summer camp, a vacation or a modeling job the most, forced meetings, forced to move which may involve stealing your things, arranged marriages...)

Just taking you to a place for different reasons (under false pretense) of those told to you is already bad. Making a person go with you because of threats or 'incentives' too. Taking you to a place you won't be able to leave without their help, like another country. With intent to permanently keep you (and never let you near your family and friends again)

Block the passage/door, invade personal space, surrounding places, ganging up, traps. Stop a person from leaving a place or taking her here against her will, 'retrivals' and 'escorting' also count. Imprisonment ultil you agree with their demands or is under their control.

Hostages (don't have to kidnap, can be someone that was in your custody before the conflict started).

Any restriction to a person's freedom. Guilded Cages (marriage? a puppet king?), forbidding to have a life (education, hobbies, fun, friends, to travel, isolation, certain jobs), forbidding to anything for a bad reason (contact with people, go to a place, being locked for your safety or usefulness)...

Servant Race (looking at everyone who mocks Hermione's anti-slavery moviment).

Locking up people because they are 'different', 'crazy' or 'unnatural' (most likely a prejudiced group) Ex: monasteries, asylums, reformatory camps...Not only that, but anything done to 'fix/cure' them, like devices, surgeries and treatments.

Being in another territory, or services like Hospital, Towns and School, even if it is from an 'ally' is dangerous, same thing with their people (doctors, drivers, professionals of any type).

Any Binding of sorts, by seals, contracts or magic or whatever. And breaking willing bonds against the person's will too.

Incapable of Disobeying

Attempt on gain the custody of minor for bad reasons. Children of powerful people have the powers/bloodline/heirship/propriety/alliances but are easier to control and manipulate.

Any forceful adoption: taking children from parents to be adopted into families you have control of, taking a bastard child away from their mother, taking any child in your custody without their consent (even if you are related/has the 'legal' right to). Maybe a reveal that your 'adoption' is pretty much a kidnapping? (Loki and Xanxus both sound like this to me, Theon too).

The person is change of you is revealed to have bad intentions? Want to create a matyr hero, maybe?

Ownership or Claim over an person or people (Bloodline? Recruitment? Human Weapon? By Association? Nationality? McGuffin? Custody between parents?)

Forced Marriage or Mandatory Fatherhood/Motherhood. (To 'continue the bloodline', a alliance or some shit like that)

Destruction and Invasion

Set a place in fire (house? comercial buildings? orphanages?)

House (or Room) Invasion and Trashing, messing on people's things without consent, uninvited guests. Trespassing private propriety in general, invading a space you are forbidden to go into, appropriation of buildings or other places (public? religious?private?), wanting acess to said places, forced housing (like that law about soldiers, thankful its no longer valid).

Destroy propriety and places (especially important and 'simple' ones, like libraries, burning books, clothes, hobby materials, documents, with sentimental value, or worse things like medicine). Not even when its 'accidental' careless excuses, don't touch people's things alright?

Sell/Throw away other people's things for any reason, like not respecting their choices (food, religious pratices, hobbies, books).

Another Things

Everyone loves bashing the 'Hero Faction' and so do I.

Unhealthy Obsession

Toxic Relationships (neglecful? clingly? delusional? imbalanced? obssessed? smothering? controlative? pushy? attempt forced reconciliation? expectations? selfish? doormat? fangirl? clingly? manipulative? False but keeping appearences?). Friendship? Romantic? Parental? Leader?

And people in a bad relationship, even if they are the victim, can do bad things because of it and refuse to leave the relationship. Can even begin unaware used against you.

Both Lysa Arryn and Sawada Nana are exemples of this. Worse, they are mothers, and mental ill for sure.

Doing something without a person's consent, awareness or knowledge. Honestly, 'needing' to sacrifice a person in some way is and always will be fucked up.

Dragging a person back to the bad situation they ran away from in first place.

Put reputation above safety, people lives and feelings (like refusing to cancel a event, deny a divorce or attempt cover up, a cover up, refusal to let people leave when in danger, in situations like death, rescue and injury)

Force an person to use an dangerous power without thinking of the consequences. Force a Traumatic Power Awakening. Attempt to learn the Secret of an Power.

'Feed' on an person's lifeforce, use their energy to power up yours or something similar? Stole their power/magic to give to another?

Unethical Hunters/Collectors.

Indiana Jones, Museums and stuff.Tourists being assholes (like taking 'souvenirs')

Wanting people to sacrifice or risk themselves for your own benefit. Or calling them selfish for thinking about themselves first or doing something for their own benefit (maybe something they used to do for another people's benefit?)

Telling a secret that is not yours (about plans? Existence? Location? If you are a professional, than its ilegal)

Turn everything (people, mcguffins...) into weapons or source of money.

Make everything about yourself. Make yourself the victim when you aren't.

All of the Other Reindeer Trope

Fostering a foster child for bad reasons (like free labour)

Be creative when creating your own fantasy world problems, here some ideas you can adapt:

Society and Culture

Bad Working Conditions.

Nationalistic Ignorance

Matyr Culture. (And all this duty to country bullshit)

Any danger a Secret Society presents to clueless innocent people.

A country's superiority and their right to rule/choose/have authority/even 'save' other ones.

Fantasy Capitalism and attack on everything that threats it in some way (libraries and free knowledge, community gardens, unions, lab-made diamonds...)

Insist that another character is 'lying' or 'just confused' about something and refuse to investigate/try to silence them. Happens often with children.

Religious/Cultural Appropriation and Modification. (That include monuments, objects, songs, rituals, words...)

Refusing/Closing researchs and pretty much anything because it goes against your 'beliefs'.

Insist that another character is 'lying' or 'just confused' about something and refuse to investigate/try to silence them. Happens often with children. Ignore or mock a person's knowledge. (Scientists did it a lot with some natives about their own history, medicine and culture). Believe yourself to know more than people with experience on this. (maybe they have a problem you don't?)

The denial of truth (Biology? Science? History? Origins? Problem?)

Calling people 'mad/hysterical', 'inferior' or 'unstable', (mostly happens to women and disabled) to justify their 'incapability' of making their own decisions.

Control the information taught in the schools/history. Keep information from people, therefore putting them in danger. (Its work related? About a product? Scientists?)

Many fake facts and rumors about prejudiced groups still taken a real today, even in professional medicine, it really bad. Mostly for the vilification or attempt control.

Put a person with special needs, or any person really, in danger/pain because of 'belief' or ignorance.

The classification of what is 'Unnatural/Natural' and 'Pure' in a society.

Anything cruel, (like abuse, assault, murder, prejudice, cruel punishment, rituals, some ideologies, multilation) being done by the sake of 'tradition' or because its 'natural', the whole 'its was always done like this' bullshit. Honor-Related abuse in general. Also religion as a justification for this.

Created a mess at someone event (like a proposal at a wedding)

Authorities

Imposed authority and orders.

Make an country go into civil war or war with another for benefit/profit.

Military, there so much problems. (I am pro-veteran and anti-millitary), the whole enlistment = free college is a fucking trap for poor people.

Deny acess to important things. (Like information about the problems/situation, medicine, education, some places, jobs). Hide information about something because it benefits you (about a product? A food? A experiment? A operation? Mission? Goal? About people's own biology?).

Being forced to put up with an bad person's bullshit because your Leader refuse to punish them/acknowledge them as evil or easily forgive them. If they try to make you 'befriend' said person aka let them into your house, with acess to your things, begin easier to do shit.

Defending a bad person and refusing to acknowledge it, expecting you to forgive and let them hurt you without fighting back.

Like the Minister of Magic or Shield trying to 'confiscate' the miraculous, or a zanpakutou. Or even Dumbledore with the Philosopher Stone. Or trying to have some 'control' over a 'magical creature'.

The Guys in White from Danny Phantom are the worse villains cuz they are 'legaly' doing crap. Interrogating, kidnapping and attacking people, invading the houses and stuff.

Ministry of Magic having Magical Nazis in their ranks but leaving them be because they are rich and noble, ignoring everyone's warning, wrongly punishing people and silencing them, forcing students to put up with spies and clearly problematic people in power (like that fucking toad and the Death Eaters like Snape), therefore making laughable easy for them to kidnap/attack students, people being allowed to do as they please (hurting your friends, family and innocent people in the process) and you being forced to sit down and do/say nothing because the Authority says so, refusing to check the Dark Mark, punish pureblood Death Eaters or give Sirius an trial is the most realist shit in HP.

Your Leader/Ruler is either an inactive idiot or an asshole and the characters are forced to obey their orders and decisions.

Ignoring a crime because it benefits you (looking at you China government about bride kidnapping). Or keep a cure, a eco solution or something like that a secret for the same reason.

Destruction of Evidence that goes against you in some way (your beliefs? Your ideals?)

The Law Enforcers take the side of criminals against the victims. (Like giving back a kidnapped victim back to her kidnappers)

If you going to have a Evil Tyrant, you need to plan their actions (force the people to build them something? Steal their labor and lands? Maybe they want the lands to build their evil invention?)

An Cover Up (specially when involve the villanization of the victim, like I saw in a few HP stories where the wizards aka the 'good guys' put drugs on dead muggleborns students, making their families lost their jobs and reputation. Or an Danny Phantom one where his family is murdered and he's kidnapped by evil scientists, who put the blame of their deaths on him).

Unhelpfull Characters

Useless and stupid adults in general, who could led their children into dangerous situations without care. If a guy/gal showed up asking about my kid, to have a private conversation with them or a 'intership'/special school without signing up first. I will bury them into my garden, weirdo.

The Fentons and Sawada Nana are the best example.

The annoying character who just do crap and refuse to listen good advices, fucking up the entire plan.

Naive, dumb, petty, pushy or delusional characters.

Passive Character who don't do nothing.

Disrespect the privacity of people and will, like letting another person mess with their things/room/house, telling secrets that are not theirs, forcing you to go to an place or with an person, worse if its an parent.

If any of those things is done to an minory group (or vulnerable ones like the poor, pregnant, disabled, refugees, orphans and children) because of prejudice, even worse.
