It's OK that Jason Todd continues to live.
I mean... DC's track record with keeping dead people dead is pretty teh suk. Honestly, it was kind of crappy of them to bring back everybody... Ollie (who died nobly and stuff) and Hal (who really didn't) and Guy Gardner, and Superman, and Lex Luthor and half of krypton... well, you get the point. But Jason Todd stays dead?? That's just... not consistant man. At this point, the only people in the DCU who have remained dead are Bruce's parents. Which is another rant for another time.
But really, Bruce has been beating himself up for YEARS over Jason. Now he gets to beat himself up in an entirely new way. Oh waa, I let him die, and then he came back evil, and I'm sure *I* must have made him that way...
I think anti-social anxiety medication would help Bruce.
