worst thing about the sukuna is evil for evil's sake gimmick is acting as if the only flipside is calling him a good person because apparently its too complicated to grasp that acknowledging the reasons a villain is the way they are isn't equal to their actions being forgiven
Sukuna would really do the most inhumane evil terrorist acts ever and then randomly let slip that they used to dunk him in molten liquids as a child because he was a mutant freak before moving on like nothing happened
