Fuck clan murder, that could possibly be justified, but there is no possible justification for what he did to Sasuke. He didn't just kill their family, but mind-raped him with subjective-twenty-four hours worth of visions of him doing it TWICE, and went out of his way to turn him into Guts from Berserk. Which means ruining his life in every possible way.

And he get lauded as this GREAT BROTHER for doing it? Fuck, Kishimoto has a warped sense of morality.
