The part that tickles me about sukuna is that he’s a massive hedonist yet failed to realise and confront something he’d been chasing for this whole time (a fellow monster/companion) because it would been challenging the belief that he doesn’t and has never needed or wanted others, which would meant facing that he didn’t get it and it mattered a lot to him, actually.
Says flocking with others brings weakness yet integrates his most favoured opponents moves into his own style.
Sukuna says others are merely a pass time until he dies yet goes out of his way to continue living past natural death so he can see and experience sorcery from another era aka fight and meet other sorcerers.
Uruame, a loyal monster who follows him unconditionally, could’ve been something but there was a distance in their relationship still (uruame has him on a pedestal and sukuna refuses to entertain that maybe he wants more from people than use).
He refuses to change and lives stagnantly for it until he is killed, only then when there’s no point in denying that part of himself does he accept the possibility of changing and companionship. He accepts the possibility of change only when he no longer alive to actually live that change in this life.
How are you gonna be a self-sabotaging hedonist?
this is what i love about sukuna honestly. the contradictions in his character are an active feature of who he is. sukuna is two-faced until the very end— not in the sense that he's disingenuous about who he is/what he desires (i have no doubt that he does truly believe that what he says is true), but that two seemingly contradictory readings of him and his actions can exist at the same time. he has two faces, not a mask, which means that he can simultaneously be a curse and a human, a calamity and a person, the devil and a god, detached from society while being fully shaped and reflective of it, having attained enlightenment while also having a distinct emotional immaturity. while i do believe that sukuna is a character best analyzed through doublethink, i do feel like him being a self-sabotaging hedonist makes a lot of sense if you really break it down a lot...
sukuna's self-sufficiency and his ideology around strength join very nicely to deliver this horrible lack of emotional self-awareness. to put it simply, his self-sufficiency has rendered it so that it's unimaginable to him that he would "need" someone else to fulfill him emotionally, his belief in might makes right makes it so that he goes completely unchallenged in this assumption. this metapost by irwd2 puts it really well:
But, at the same time, it seems that he finds it very difficult to look inwards. Whenever someone says something or has some attitude that goes beyond his ability to cut and slice what's in front of him (in short, makes him have to face his own curse), it seems that he has a couple of small seconds of reflection and after that returns to his normal state of violence and demonstrations of superiority. (tr. by me)
every conversation sukuna has happens with his explicit consent. there is no way to force sukuna into facing himself, no way to really change his mind, because he is so powerful that he dictates the terms of the conversation. if it causes him discomfort, he will just kill you. if he finds it offensive, he will do the same thing. it's why yuji pisses him off so deeply, because he's a problem he can't just solve by cutting this time.
at the same time, it is the exact same factors which create the conditions for his hedonism in the first place. his overwhelming self-sufficiency makes it so that sukuna always puts his own desires and needs first. to him, he's the only one that really matters, and focusing on others and actively taking them into consideration when making decisions undermines his own self-sufficiency. he doesn't need anybody's approval, anybody's help, and doesn't care about any of their opinions, because if he did then he wouldn't be fully self-sufficient. there will always be external factors (other people) influencing his decisions, and his own autonomy is something sukuna refuses to give up. his belief in might makes right and his own strength gives him the ability to actually be self-sufficient and hedonistic in this way, and makes it so that his hedonism is ultimately justified in his eyes. if he's the strongest, then that means his ideology is correct, since there is no way to concretely enforce another truth upon the world.
honestly, i'm not entirely sure if sukuna's hedonism is even actually hedonism, i feel like it's more accurately described as egoism/stirnerism/yangism. hedonism is the pursuit of pleasure, but sukuna seems to be more motivated by the pursuit of self-interest than anything else. or maybe there's another philosophy that more accurately describes his deal than what i know of. but i digress, either way, him being a self-sabotaging hedonist makes perfect sense because these traits ultimately come from the same root cause.
the only way to end this cycle of curses was to kill him, haha. this truly was our jujutsu kaisen
sukuna was doomed to be this way because of who he is fundamentally. now how he came to adopt these ideologies is another story entirely...
