dents character was perfect: everything he believed in and stood for crumbled and fell away from him - his whole world pretty much disappeared around him. he was left with nothing but the thoughts of what could be and what should be. of course he is going to be mad
plus, dent was so angry at the end, he was going to kill himself second but his coin flipped to the good side, so he moved on to the next. it would be stupid to keep harvey in the second movie cause he would have turned into the very thing he was so pissed off and hateful about - the loss of hope. harvey would have become the very thing he loathes if he stuck around, and would have really destroyed what rachel stood for.
