David is a skilled master manipulator as he uses his charm and good looks to trick and using his friendly façade to trick others into trusting him for his own personal gain. He is narcissistic psychopath, extremely selfish, incredibly violent, petty, murderous, and obsessive as despite his usual calm demeanor, he gets angry very easily over the smallest of things, and when he doesn't get his way and when someone crosses him or doesn't respect him he ends up doing horrible things.
