No victor? He had foiled Joker's attempt to cause mayhem, had captured (or lead to the capture) of the Joker, had defeated/killed Two Face. Yes, he was blamed for the death of Dent, and "quote" will be hunted down.
Kinda like it could be IMPLIED that Spider-Man would be AFTER Norman Osborn's death in SM1. *go figure*
And as Ajendo already pointed out, TDK's storyline is lifted from what should of been Spider-Man's birth right.. IF we would of had a Director that had chose to have taken a serious approach to the characters and storylines, as opposed to the kid friendly, carebear approach we got.
