If Sasuke became the goody two shoes early in this series then there wouldn't have been any plot. I liked it as the original plot that was delivered by Kishi and that is pursue your interests on your own until you have proven wrong. If Sasuke accepted Naruto as a friend and an equal then couldn't have felt Naruto's pain or vice versa.
But I think it would make more sense because of itachi saying "You must kill your friend." I meaning I don't want Sasuke to be licking naruto shoes but I still think it would make sense.
No. I think it was perfect that Sasuke denied any feeling toward Naruto until Chapter 698. The signs that their friendship was not one-sided were there, but they were subtle.
Yeah I think it would have been better if Sasuke was a little more friendly. In part 1 he could have been nice towards Naruto and then from Vote1 on he could be the more emotionless Sasuke that we know. That way the loss of him would have hurt more.
He was never that receptive to Naruto so I always felt that the claim that they were "best friends" was a little forced.
