Nolan also did not give a fuck as long as it made for a cool shot. On top of that he pretty much lied to his audience about the character but the character lies to himself constantly. I won't kill you but I don't have to save you either is dumb as fuck and makes no sense. He put him in that situation, he is responsible for his death. But unintentional, right?
Or how about blowing up that compound and killing dozens of members of the LOS and the farmer as well? Ohh well unintentional. Talia and her driver? Fuck this, I want that bomb and if it means killing you two; tough shit. Chasing the Joker...hey innocent truck driver, you are in my way. Wrecking you and your car, unintentional though. Harvey, I liked you but that kid must live. Soooo, bye *tackles him to his death*. If you find all of his kills excusable...well then. Must not be so hard to come up with excuses for Batfleck, right?
