We're talking about Uchiha's here, and an entire clan.

Gaara was kinda mad, Neji suffered from his father's death, Nagato was pretty much the same as Naruto, and Chiyo... heck she was about to die anyway, might as well do something with the life she had left.

But the Uchiha? Too many people, and what had they lost? Not a single person.
They were out for revenge because of their humiliation, not because of personal loss.
Persuading a clan of such arrogant elitists would be near impossible.

And what are you talking about, Sasuke? Sasuke is still emo, the minimal change that Naruto had on him was for naught.
