question... why was everyone so "omg! he killed someone (joker)" about robin killing the joker when batman was trying 2 kill him 2? like, in the beginning old bruce throws a bat-a-rang thing which cuts off a card-board (or something) two-face's head. and back in the flash back he throws a knife at the joker's head. were they only all "omg!" cuz robin, who's a kid, did it? even if that is, robin joined batman and batman would have had 2 expect something like it or something close would happen so..... eh.... confusing...
