Ultimate Marvel Hulk is much different from the normal Hulk, he usually tends to cause harm to innocents. But he does act in a heroic manner once in a while and helps out whenever he's really needed. And despite his sadism he does regret his actions once in a while. This version of Bruce Banner is also very complicated, as he is very abusive towards Betty and has caused harm to millions of people. But even Banner has his limits, as he has shown regret for many of his actions in the past.
