Hey, she tried to stop. She did. There is no real equivocation when it comes to this. If, in the snow, Naruto had accepted her, she would never have gone back to Sasuke. Because that would have hurt Naruto, which is something canon had clearly established she was not willing to do under any circumstances. Something she would even die to stop from happening. Naruto simply didn't accommodate her wishes. She wouldn't have been with him if Naruto, or anyone else for that matter, had given a damn about trying to stop it. But they didn't. They only cared about Sasuke.
I'm way pass the part when Sakura begging like a pathetic whore asking for the man to take responsibilities and i'm not talking about the desperate confessions. My point is why they make Sasuke says all those things about hes not interested and shes daydreaming bla bla bla when she still conscious , why not say all of that to her face directly so she can hear it ? why knock her out cold then say all of that it's pointless if she can't hear it. The point is Sasuke not interested and want Sakura to stop chasing her so he should listen to what hes about to say. I think that is the rule of talking / negotiating , you talk first , you reason first and if they didn't listen then you resort to action because at that point talking is useless. Sasuke should tell her all of that and when she still not listen you can chidori her. My point is they trying so hard to keep everything hidden and secret .... it's near the end everything should be solved , tying every lose ends.
The fake confession , the fodder nin confess to sakura and image of sasuke comes lead into that ... i'm already accept the fact that ... okay maybe i'm reading the manga wrong maybe that is the sign of impending doom. But stop with the lies if they gonna make NH and SS cannon do it legit way , not keep everything secret , let Sakura knows , don't make Naruto fall in love with Hinata with genjutsu , why can't they do it the legit ways? they have to make NH and SS happen with lies ... that's sick!!
