I think he may be more interested in a chaotic dog-eat-dog scenario in which he can be the strongest figure amongst all the anarchy. I'm sick of the mob, I really want to see Zsasz return or Mad Hatter make a
cameo. Not a starring role, just a kind of extended cameo. And the way to do this would be for Bane to get rid of Batman and just open the floodgates. Beating Batman might not be enough, to
fully defeat him, he may want to utterly ruin the city that Batman cares about so much.
But at the same time, he shouldn't be a 2D 'evil' character. Remember, the guy who broke Batman's back is also
this guy:
He has to have a sense of honour to go along with his ruthlessness. Kind of like Simon Gruber in
Die Hard With a Vengeance when he becomes slightly offended at the suggestion that he would kill children and protests that '
I'm a soldier, not a monster. Even though I sometimes work for monsters.'
