This.I wouldn't be surprised if he did...but I don't want him to do that...its too clichéd for a villain to turn anti hero in Shonen.
Anything is possible, Aizen will most likely play as a antihero just like what happened to OrochimaruF*CK NO!! kubo would never do some stupid sh*t like turn great lord aizen into a good guy. after all everything thats happening is all a part of his plan to kill the soul king and take the throne. ywach is just a pawn
im 100% positive that won't happen. aizen isn't the type to be an antihero. orochimaru lost so he had to change but i mean just look at all we've seen of kaizen since he was defeated. he acts like he's still in the game. he acts like he's still winning. ywach offered to free him and he flat out refused and then to add insult to injury he messed with ywachs mind just to prove that he wasn't powerless.Anything is possible, Aizen will most likely play as a antihero just like what happened to Orochimaru
Pretty much this^Old bad guys always come back as good guys when new bad guys threaten to destroy any and everything.
I think I might actually drop Bleach if this happened.
