Bane is not the anti Batman in the comics. Bane in the comics has a completely different set of ideals to the one in TDKR. In the comics Bane doesn't care about corruption, or the wealthy, or bringing justice to anything.
Bane came to Gotham to prove he was better than Batman, and take it over and run all of the criminal enterprises. There was never any parallels drawn between him and Batman as being mirror images of each other.
The only villain I do see a real black vs white contrasts made to is Batman and the Joker, in that Batman represents order and Joker represents chaos;
