I've just reread some chapters after read the latest, and I don't know why, maybe because Sukuna's past hasn't revealed yet, but I can really see him as an "evil". yes, he is killed people and living just based on his pleasure and displeasure, but he was human a century ago, there's must be reasons why he had to thrown his humanity and became a curse, a King of curse on top of it.
Sukuna's past arc the only thing I need right now ಠ﹏ಠ
GEGE FUCKING DID IT! HE REALLY TAKE THE WRONG TURN! IT'S ALL FUCKED UP!
