Because if Naruto dies, so will he.
If you are talking about abilities and power yes probably counting he has the nine tailed fox especially now that this is naruto shippuden
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."
no, not yet, but Naruto did said that he will die with Sasuke.
Never- Naruto wants to save and bring back Sasuke
no, sasuke defeated naruto, but he did try to kill him.
Naruto can only die from the Nine Tailed Fox forms if: his cells over grow (mentioned in Shippuden) from rapidly healing him or he enters the Ninth Tailed state or likewise if the Akatsuki removed the demon. And besides, the eighth tailed was never meant to kill him
