Another Naruto Question
 

In the episode where Itachi kills his clan I felt he was lying to Sasuke when he told him why he did it. Can someone tell me his true reason for killing his clan and not killing Sasuke without revealing too many spoilers.

You could continue watching the anime to find out, I guess. I wish I could help more than just saying that, though. Maybe try googling it, or asking on an anime board?

Man, I'm tempted to post an idiotic theory based on this now... :lol:

It's been a while since I read all this stuff. I think Itachi wanted Sasuke to become a warrior who could compete with him or something like that.
I can't believe I liked this series...

I think what he says it true pretty much. He wanted to test his power but since he felt that Sasuke had potential and could be a match for him he let him live.
