Of course it is. He does shit alone, just wait and see.there's no need for Sasuke to be evil
No matter what power up he's gonna get, Naruto's gonna foddarize the shit out of him U_U
I wouldn't say he's evil, but he's going to have to clash with Naruto at some point before the manga ends. Kishi said that he'll tell the stories of the Juubi, then Madara, then Sasuke, we've done the Juubi, now we are on Madara, meaning after Madara, we focus on Sasuke, cause he definitely has some kind of hidden agenda.
IIRC, he said that it would be first Madara, then the juubi, and then Sasuke. The next arc would probably explore the Sage family, like what happened to the brother and all.
Madara became power-hungry. So you don't think Sasuke will get power-hungry now that he can do this shit? Sasuke and Naruto WILL fight.He's not power hungry anymore.
