Re: Characterization of the Knight - Nolan and Bale's Bruce Wayne/Batman - Part 2
Another point being that Bruce couldn't keep going on as Batman. That was it, physically it was his swan song, and mentally he finally let go the pain that was burdening him. He managed to do what he set out to do, to inspire people and give them hope. If Gotham would need Batman after all of that is still debatable, but if the situation arises, and neither the cops or the system could handle it, there is still Blake to join to the fray. But it is up to him, Bruce didn't force Blake, he just saw his potential and left him with a choice.
A hero can be anyone. Even a man doing something as simple and reassuring as putting a coat around a young boy's shoulders to let him know that the world hadn't ended.
