Possessing a vast ego and a god complex, however, Bison is physically incapable of feeling empathy for others and even takes pleasure in watching people suffer at his hands, never feeling a shred of regret or remorse for the numerous atrocities that he has committed. In many ways, Bison's characterization is comparable to the clinical diagnosis of a real-life psychopath. Bison's malevolence and sadism are reflected in his iconic smile, a very wide grin that exposes not just all of the teeth but even the gums as well. He occasionally refers to himself in the third person (possibly to emphasize his own sense of self-importance) and displays a twisted sense of humor, as well as a "business before pleasure" attitude.
