Spoilers? maybe? I just read somewhere that Jason Todd came back from the dead and was the Red Hood. But then Jason strapped bombs to the Joker and asked him why Batman never killed Joker... and then Jason gives him a gun and points a gun to Jokers head and says if he doesn't kill him in three then he will...yet Batman throws a batarang and slices open Jasons neck? So he's dead and Batman killed him? Doesn't that make it seem like he went back on his world of ever crossing that line that he was trying to prove to Jason?
