So why would Bane hate Bruce if not for Talia? The film mentions to us that Bane was excommunicated by Ra's and then randomly has him saying throughout the film that he wants to fulfil Ra's Al Ghul's destiny. And yet we are never even shown a reason why he would be so dedicated to fulfilling Ra's Al Ghul's destiny or why he would be so dedicated to the League of Shadows. Batman Begins managed to effectively show us why someone like Ra's or Bruce would be attracted to the League of Shadows philosophy, why not show the same for Bane? Also, if Bane is so dedicated to fulfilling the destiny of Ra's Al Ghul, why attack a city that isn't even corrupt at the time? There are so many inconsistencies with the Bane plot than the only unquestionable reason shown for why he attacked Gotham is because of Talia. I understand that everyone is going to have their interpretations, but they always seem to fall to conjecture
