What Sasuke did is much more stupid. Going off to kill a bunch of people who had nothing to do with the death of the Uchiha..and listening to the guy who helped pull it off. Nagato's redemption was more because he was never really so much evil as he had lost his way following Yahiko's path. But Naruto's become so emo now I don't really care much for him anymore. Which is still better than Sasuke suddenly becoming evil for no apparent reason except for finding out Itachi wasn't. IMO anyway. But both still suck.
