If sasuke gets credited with stopping kabuto and therefore helping the shinobi alliance, he might get pardoned after the war and no longer be treated as as a criminal
Maybe, but I still think konoha jail is the best place for him. He'll get some time to think of all the bad things he's done. lol. "timeout sasuke! And no supper before bed, either!"
On a serious note, he should be punished somehow.
