There are fair critiques to be made of Nolan's version of Batman, but this isn't among them.
I got the sense that was his main motivation. That's why he engineered the whole thing with Harvey Dent. He wanted
to give up being Batman. So he could be with Rachel Dawes. But he couldn't just give it up willy nilly. That explains the whole plot of The Dark Knight. Begins was all about proving he was the real man he was inside, again so he could be with Rachel Dawes "It's what you do that defines you". He spends the whole trilogy completely pussy-whipped.
