You're not even trying
Zuko sending Combustion Man after the Gaang was wrong but you're conveniently ignoring why he did. Azula lied to Ozai about Zuko killing the Avatar, fully aware that if the Avatar ended up being alive, it would be him, not her, to face the backlash, humiliation, and abuse for it. Zuko was trying to prevent himself from being abused. Seeing his face (ya know, its permanently mutilated), its understandable.
Azula had no reason to do this cuz she didnt have to worry about it. She also had no reason to steal from anybody cuz she was a princess and had everything already handed to her. Zuko was lost, on the run, and homeless. Wrong, but he didn't do it to be cruel, he did it to survive. His actions are sympathetic.
Again not gonna reply if you respond, just dropping facts you forgot.
