Not only does he believe it's his duty to destroy Gotham, he believes it's his duty to punish it for past misdeeds, again reckoning was a very specific word choice. He's calling himself the personification of Gotham's judgment and punishment. What other past misdeeds are on the table here? Ra's obviously believed Gotham to be a corrupt city, Bane talks about fulfilling his destiny. Can you at least see how this is a logical conclusion to draw, even if the movie doesn't spell it out by having Bane say "I believe Gotham is corrupt" in private? There's a difference between interpreting something in a film and finding something to be implicit. I truly find Bane's belief in what he is doing to be the latter. And of course, Talia has a role in his actions too. I'm not denying that.
Now, whether Bane never let go of his initial LOS indoctrination, or has a reinvigorated belief thanks to working side by side with Talia ...that is open to interpretation. But all I'm saying is I think the movie makes it exceedingly clear that Bane has stake in this, ideologically.
