Since you talk about how Azula was mistreated in the comics (I 100% agree with you), I saw this take about comics Azula so here:
“She was given a chance at redemption, but she decided to kidnap kids and use them to gaslight and manipulate Zuko into becoming a ruthless leader like her father. Pure evil.”
In what fucking world is being locked up in an ABUSIVE asylum, where you're tied up and beaten for no real reason, for at least a full year, with the people responsible for the abuse you're suffering showing up to gloat in your face and then act like you're satan for not liking them much "being given a chance"? The fucking writer of said comics literally said the point of that place was to make Azula WORSE.
He wanted her as a villain, realized it no longer made sense for her character to do anything against the Gaang, or anybody, post her breakdown, so he gave her a new motive to hate them - he just didn't realize it was one that made TOO MUCH SENSE. It'd be like if the showrunners had expected us to say Zuko only didn't deserve to be abused by his father because he would eventually become a good guy and not because abusing people, especially children, is wrong.
Show!Azula is both an evil person and an abusive victim, with neither aspect of the character being the responsibility of the heroes, since they were not the ones to indoctriate her, they're just the targets she was taught to hate.
Comics!Azula is a monster THEY created. They saw a fallen enemy that had already lost everything, including the will to keep fighting, and decided to make her worse than she ever was instead of helping her or even just leaving her alone.
Literally none of the bad things she does in the comics would have happened if they had given her proper treatment, then decided what to do with her based on if she willing to change after a full recovery.
There's nothing merciful, heroic, honorable or even morally neutral about what the Gaang put Azula through in the comics. They all went through horrible character assassination in which they become hypocrites that PREACH about mercy and second chances and redemption, but in PRACTICE will abuse anyone who is not already on their side because they think being beaten into submission is the same as being healed. This stupid fandom just argues otherwise due to a hellish combo of ableism and stan nonsense.
Fuck those comics, fuck Gene Yang, and fuck anybody who defends that bullshit.
