Agreed. Even if he did kill her, it would be temparary. I could see Kishi pulling that off (kind of what he did with Shikamaru) but eventually she would be healed. Naruto would probably be the one to save her in the long run if that happened.
I think personally Obito has to be the one whose gonna save her, he realized what was about to happen. Or Sasuke...though i cant explain why i think that lol there was just something about the way the panels flowed where Kishi might give him a chance to redeem himself somewhat and save her (which would look good for him after he tried killing her...though i dont know how many people know about that)
