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
I think you just answered your own question. We've seen the League of Shadows and the types of people they attract. People who have suffered injustices and are basically mad at the world. Given Bane's circumstances, it's not hard to see why he fits the bill. The fact that it's Ra's who actually rescues Bane from the Pit pretty much makes Bane the ideal candidate for a LOS devotee.
Another thing is that sometimes there is intended ambiguity in films. Now, we can sit here and argue all day about Nolan's intentions I suppose, but I really don't believe he intended for there to be any ambiguity about why Bruce quit being Batman. He says why, point blank in the film. With Bane's character, Talia's reveal creates some ambiguity, and this just invites us to take a look at all his words and actions in the film and examine them more closely.
