Re: Batman Begins v.s The Dark Knight Rises
There is one moment after the Talia reveal that solidifies that Bane is not just some henchman for her. It's when she tells him to keep Bats alive so he can feel the fire then says goodbye to Bane. What does he do? He doesn't obey orders, he's his own man, and he tries to blow Batman's head off anyhow "we both know that I have to kill you now...you'll just have to imagine the fire".
