If Sasuke turns a good, that will be to much BS for me. I hate happy fairy tale endings for people that have done evil things, Sasuke redemption should be death, not this crap, oh we forgive you now.
Sasuke had killed Samurai, attacked Kages (which is like attempting to kill the president), attacked ninja from every nation,almost killed Kakashi,Sakura,Killer Bee, was part of international terrorist group.
All he cares about is family, he should die, and be happy being in the afterlife with them. Happy ending for Sasuke, sort of.
