Yes they do unfortunately.
I don't think Sasuke and Naruto are gay with each other, and Sasuke does try to kill him at TWO points in the series, so i don't think it'll happen.
because sasuke is naruto's friend and he will never kill him
No Sasuke does not kill Pein
Last time they meet they tried to kill each other.
Well, this is just my opinion:No. Sasuke will not kill Naruto.I mean, they are teammate, they was once best friend. They watched each other's back.
For right now, there is details that have been released that Naruto will kill Sasuke in Naruto Shippuden.
-SPOILER WARNING- No, Naruto doesn't die. Sasuke does manage to kill Itachi though.
He doesn't. >.<
probably...
Kabuto try to kill sasuke in "Naruto episode 51."
no, not yet, but Naruto did said that he will die with Sasuke.
Never- Naruto wants to save and bring back Sasuke
