Do you ever wonder what would have happened if Sasuke had succeeded in stabbing Sakura with his chidori-hand, that time at the bridge?
I do. And I don't think he would've killed her.
Firstly, because he probably didn't mean to hit a vital point, just to leave her too wounded to get in his way. Secondly -- and most importantly -- because Sakura would've pulled the same thing she did when Sasori stabbed her: she would have held on to Sasuke's arm and healed herself meanwhile. She would've been heart-broken -- and she was -- but she wouldn't have died so easily. I mean, come on, give the girl some credit! She is, after all, an extremely talented medic ninja, the best disciple of Tsunade, and very strong for her young age.
I also think that would have been the moment Sasuke realized -- despite his fucked-up mental state right then -- how strong she really is, instead of at the battlefield, when she released her seal. And the major turn-on would've dissipated his darkness and stuff.
