Because of his unorthodox education, Damian Wayne is not properly socialized and sees killing as a normal way of doing the work and loves doing it. In an attempt to convince his father that he is worthy of being Robin, tries to kill several of the enemies of Batman and Robin today. He takes special pleasure in inflicting violence and cruelty, as well as showing a blatant disregard for life.
