After Jason was killed by the Joker and buried, his body was obtained by Ra's al Ghul who felt guilty for collaborating with the Joker and indirectly causing the death of an innocent. Ra's used the Lazarus Pit to revive Jason but the process took a turn for the worst when Jason went on a violent and mindless rampage that took him over a cliff. It was assumed Jason had died "again" but years later he would return to Gotham under the moniker of the Red Hood. Jason no longer identified with Batman and made it his new purpose in life to clean up the streets of Gotham of crime. But instead of doing it with a code of honor like Batman, Jason turned to executing the criminals himself. Ultimately Jason wishes to kill the Joker since he's the reason he died in the first place.
