Possible Spoiler ( I don't know if you read the manga or not)
Naruto does not want to kill Sasuke, but finally understands that talking alone will not reach Sasuke. He agrees to fight Sasuke again, and tells Sasuke that that is the only way they will understand eachother, and also claims that both he and Sasuke will "die together". For a better understanding, it's best to read the manga.
naruto want to kill him
because sasuke is naruto's friend and he will never kill him
No Sasuke does not kill Pein
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."
yes in the original naruto, not shippuuden, in episodes 130 (130 is just flashbacks, it really starts at 131) to 135, spoilers Naruto loses cuz he doesnt want to really kill sasuke, and sasuke doesnt really want to kill naruto. (cuz itachi told him to kill naruto, and sasuke never listens to itachi) so sasuke just knocked him out after he used all his chakra. he also cheated (not really, i just hate him)
For right now no one dies, but in episode the closest was in episode 260 when Sauske defeated Naruto but chose not to kill him.....
Never- Naruto wants to save and bring back Sasuke
no, not yet, but Naruto did said that he will die with Sasuke.
