Bane is stronger than Batman but he’s basically a miserable sort of person, pining with unrequited love for Ra’s al Ghul’s daughter Talia, crippled by mistreatment in his youth in a dungeon-like prison where he was cast unjustly, his face invisible behind a mask he must wear continually so as not to collapse in agonizing pain. Insofar as the audience identifies with a villain like that, it can only be out of sympathy. No one in her right mind would want to be Bane.
