When does Naruto kill Sasuke?
Never- Naruto wants to save and bring back Sasuke
In Naruto, Sasuke attacked Naruto on the hospital roof with his Chidori, but was interrupted by Kakashi, who noted that attack had intended to kill or seriously injure. Sasuke also tried to kill Naruto twice in Shippuuden but was stopped by Orochimaru, and then Zetsu and Tobi. As for the future, Naruto told Sasuke that the next time they fight, they would both die.
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)
Sasuke doesn't kill Naruto. In the last few episodes of Shippuden Naruto kills Sasuke in a fight to the death. If your talking about the big fight at the waterfall I don't think Naruto actually dies. He just gets really hurt. Sasuke did that because Naruto was trying to stop him from leaving so they got into a fight. Also, it was to see who was stronger.
Sakura has never confessed her feelings, but she has at least shown that he's more important to her than Sasuke. When Sai told her Naruto loved her and Shikamaru said he was going to kill Sasuke, she said she would convince Naruto to accept Shikamaru's plan. She's also tried to kill Sasuke herself. I think her feelings for Naruto are obvious, but there still isn't any 'proof'. - She finally confessed, but Naruto didn't believe…
sasuke will kill the bad elders and when sakura goes to the fight sasuke with danzo, danzo will atack sakura and sasuke willl proteck her. when they kill danzo together. naruto will come and sasuke they will beat up madara and naruto will became hogage and marry hinata, sasuke will fall in love with sakura. i hope to end like this thanks for reading my answer.
