Ok, since my ENTIRE YT fyp became Harry Potter while i havent watched it in YEARS.
I'm gonna state my opinions on here (I can foresee the hate and yap)
1- Lucius wasn't a bad father, nor a good father. my friend read the books and mentioned that Lucius spoiled Draco; for one, he wasn't abused and was loved. And also that 'Lucius forced Draco' Lucius was in Azkaban. It was completely Draco's choice. It was his choice to be a bully. His choice to be an ass. his choice to be a Death Eater.
Draco is aware that teachers are higher than him, and he might've been scared of Voldemort and his joy for killing, so stepping up against authority/people above him in power was probably something he wasn't comfortable with. 'Just like his father' Bellatrix (or whoever said that in that tower) saying Lucius was like that is shown when Lucius ran to his family after the fight instead of immediatly facing consequenses after Voldemort's demise. They live for the thrive of hurting those 'beneath' them, but once it's someone above them in power, they become a pup with its tail between its legs. 'Fake friends' Crabbe and Goyle (or whatever their names are) were NOT fake friends. He respected Harry, even if slightly. Doesn't mean he loves him, or anyone in Harry's group. And he was afraid of Voldemort, even if it was his own choice to serve him.
2- Snape saved Harry for Lily. He hated James with all his being - the trauma, bullying, humiliation and taking Lily - and Harry was the spitting image of that bron of trauma. He could've gotten attached, yes; Dumbledore told him to protect Harry, with the reminder his eyes are Lily's, without even the hinting at that Harry would have to be killed eventually. Besides that, Snape notices a lot of stuff; a fricking invisible cloak in a dark room at night, Harry noticing the already half-hiding wound on his leg, and more. it wouldn't be a shock if he noticed Harry was writing down his words in the first lesson, or that Harry indeed had more in common with Lily, or any of that. That doesn't immediatly mean he loved Harry. He was responsible for the boy, and notices stuff. It is natural to grow to care for someone then, but still.
3- Lavender and Hermione didn't hate each other. They both loved the same boy, and ended up rivaling.
anyway, the rest i forgot.
