Well he did kill Deidara, he didn't kill Haku but he probably played a big part in it (he pretty much risked his life to save Naruto, Sasuke has already figured out his movements, so we know that he was capable of defeating him, it's just that he saved Naruto instead). And Zabuza.... well two outta three isn't bad. But he was in the team that killed them as those above me said, so nothing else really matters, I mean, what would be the point of them saying "Naruto killed Haku" when they're talking about Sasuke?
And lol, yeah, who is everyone? I don't remember anyone saying that Sasuke killed Zabuza and Haku becides that one dude.
And what are you talking about with Naruto? You're totally living in the past on this one dude, Naruto gets a crapload of credit now. Just as much as Sasuke.
All in all, there isn't much of a point to this thread, because even though they didn't have it exactly right, the point of the part that I'm assuming you're talking about was to sumarize that Sasuke's strong. You put too much thought into it lol.
