My best theory is that if itadori becomes a villain it’s only if yuta/Gojo lose. If he was to see the death of two of his friends at once especially one that has already passed I believed it would drive him to insanity, to a point his cursed energy fluctuates so violently that he is capable of preforming blackflashes almost like second-nature. He wouldn’t be like sukuna of course, but he would have no mercy for megumi. He would have no mercy for curses or cursed users after that either. I can see a sort of cycle continue, from good and evil. Sukuna, true evil, turns yuji into broken evil, who then turns another into true evil, just to make another broken again. Take this theory how you will, I thought it up on the spot.
I feel like he is gonna pull a deku and fight curses and run away from the jujutsu soccers but this time there not trying to save him they want to kill him
It would be believable but Gege wouldn’t do it he wouldn’t give Yuji the spotlight like that 💀 But the fandom has made this my favorite theory now and I’m going to be sad when it doesn’t happen. 😅 I want villain arc as long as Yuji has a good reason, which he currently does.
I won't be surprised if he does go evil after killing sukuna. He's pretty much gone mad by now from all the deaths. Theory he might be the next sukuna like sukuna he will become the strongest out of the eras and the story will just do a full loop.
