It is a Self Insert IF, The point is to roleplay, why do you think DnD players play Chaotic Evil PCs? Are they actually evil losers or are they just finding fun in being a type of character that feels badass and acts as a form of escapist fantasy that lets them escape the restrictions of their daily life? The type of character I like most is one that gives off the air of unrestrained freedom, one who lives according to their own feelings and is detached from wordly noise.
Many extremely evil characters naturally give off that feeling. For example I like Sukuna more than Gojo, not because he is evil but because he acts as though he has unrestrained freedom. You think I actually want to kill people or that I actually hate Mei Mei or that I actually think being Evil is "based"? Obviously Not, I am roleplaying even here on this thread, It's a persona. Even the Wu Heir Glaze is something I do to entertain myself and the people on this thread, It brings variety. If I EVER actually played through the Mei Mei and Ai romance and If Ruo wasn't so obnoxious and glazed, I would be glazing them too to bring variety. I like to say the most outrageous things I can think of, not because I actually think like that but because I find them fun.
I play my Wu Heir as an extremely evil psychopath because I can, I like that POMA actually allows you to play any type of character and offers unlimited customisation in character personality. It isn't like those half-a*sed IFs where even if you build an evil character, they still force your self insert to feel or care about someone that your character couldn't possibly care about. I am just vibing with the cruel brutal and demonic atmosphere of POMA. If I were to play Auraclash for example, I would be the biggest haremlord you can think of even though my Wu would never ever do that.
We are all having fun here, You don't need to personally seriously name-call someone, It's rude. I really don't want to get into a real confrontation with you. If I said something that offended you, I am sorry for my behaviour.
