Given the recent event which sent some NS fans on red alert on other sites, I wouldn't be overly concerned given the fact of how sudden and just how well, anti-climatic it would be, I mean killing Sakura doesn't serve any purpose.
As I said this would reduce NH to the most overly convinent and fodder pairing rather than go forward with development and other stuff (hints like kushinas foreshadow of an ending pairing, 631 being an extension that it could be NS). My best defense to this cliffhanger in saying sakura will live is simply because she is a member of team 7, its a matter of one thing cannot exist without the other. Team 7 cannot exist without Sakura, its incomplete and the things on her end are well obviously unresolved if she dies, I mean those revived by the edo tensei practically all became resolved characters because well, they came back with a whole war of conflict. Sakura dying doesn't resolve anything, it leaves much unfinished on her side and on others. naruto cannot exactly reunite the team in the end if any die. I feel a better explanation is this:
If Sakura were to die, who would fill in the blanks, who would accomplish the stuff she orignally had? Well the romance subplot is overly simplified with Hinata as Naruto's love interest, but does Hinata fit into the whole team 7 aspect concerning Sasuke? No she doesn't. Sasuke and Hinata are polar opposites, they never interact or associate with each other. They never impacted each other, they never even spoke. If this wasn't the biggest gap for HInata, I don't know what is. Hinata cannot fulfill all the other stuff Sakura leaves behind, the whole team 7 aspect. What about Ino? She is impacted by Sasuke but has been unused in this regard so thats a pass on her. Karin, well karin fits on the sasuke stuff and knows Naruto has a brighter side but she doesn't know the whole conflict, only a bit from what she heard at the land of iron. Out of any girls with some love attribute, karin comes closest oddly enough to fitting the stuff sakura leaves behind but even then, theres no one else who can fulfill:
-Being part of team 7
-knowing the conflict between naruto and sasuke, even having an indirect impact on it (Sai's reveal)
-associated with both of them
-knows both of them and what they would do
-is in part driven by the conflict of the others as well
-resolves in supporting the two on all their hardships (well its naruto mostly at this point, sasuke is in mistrust).
Thats what I mean, how can people expect this other stuff to be focused on by anyone other than her? Hinata has no business with Sasuke, Karin is on Sasukes side for things but knows hardly anything on naruto or the conflict between the two, Ino hasn't been presented enough, its just a mess of holes in stuff like this related to team 7 if she gets axed. I mean doesn't anyone see a big conflict on Sakura when it comes to what Naruto does/tries to do and what Sasuke has pulled and the impact this had on her? She was caught up so long in this situation of she "cares" for naruto and supports him while still "loving" sasuke but mistrusting him, this whole conflict still bypass people that if this is her established conflict between the two then the question of 'How will Sakura act if Sasuke tries to outright kill Naruto? How will this impact her? This goes unanswered cause she would be dead.
