the only people and things that are able to kill naruto at the moment are Madara, Obito and the Juubi...and this is one reason why i think naruto is goin to end up dying to save the world as his father ended up dyin to save the village father like son lol
do you think sasuke is the one thats gonna kill him??? as far as i know... if he were on the battle field with naruto against madara and obito, he'd just get in the way. naruto's BM clone would do for a better team mate then sasuke
