Well first I was like "What the..." then I turned back to this scene again. And then she 说 it... I just couldn't believe what I heard! Sakura killing Sasuke??? Was this a joke...? Trick 或者 Treat? Because OMG! Sasuke is like way up there while Sakura is... Down there, if 你 know what I mean.
But on the other hand it was actually pretty 《勇敢传说》 of her. She still loves him. It's very obvious! She just wants to kill him because it's better for him to just die than completely lose himself in the darkness. No matter how hard and painful it is, Sakura was quite strong and ready to 熊 such pain.
It's just so clear she doesn't stand a chance. I didn't really get what she was planning when she came to him... it didn't look like she was about to kill him right away... (Well at least that was smart of her).
Also she was about to make a sacrifice. She probably knew how things would have ended if 卡卡西 and 火影忍者 hadn't come. But we're all not holy, we all have a right to make mistakes.
So in my opinion it was a stupid yet 《勇敢传说》 thing to do.
I was thinking that she shouldnt want to do it alone and that that was selfish thinking. What if she were to die? That would be aggrivating and emotional for all involved. She shouldnt try to trick her 老友记 and besides i think that she really WANTED Sasuke to kill her b/c of her depression of him leaving.
