1.Please, don't be hypocrite + superfacial. Everbody know about NaruSaku fans that the 99% of NaruSaku fandom WANTED SASUKE'S DEATH from the beginning. Saying things like now makes only things worse about NaruSaku. Just say that there should be less NH and it's still better than saying things that are the opposite NS fans were saying before.
2.Sakura knew about it, she just didn't care about it because of "Sasuke-kun".
Actually, they came with the idea, Kishi said yes, the director made a script, Kishi overwritte it where he pleased (even noted that he felt they think of him as a dictator), so unfortunatly at leas 70-80% of it written by him.
Why are you here?
