The Dark Knight Rises Ending Disscussion WARNING: MAJOR SPOILERS

[Froge]

There's no real reason for Bane to be kept alive, though. What would that accomplish plot-wise for the series? It's not like The Joker, in which Bruce was morally obliged to keep him alive; Bruce even says "You have my permission to die" right before he subdues Bane (which probably evidences that Batman hated him more, or perhaps considered Bane a more serious threat).

On a side note, we never saw the Joker going on any of his shenanigans when Gotham went anarchy mode. I'm guessing they hung him /firing squad after the end of Dark Knight?
