He's sadistic, masochistic, two-faced, and doesn't care about anyone. He was also born clinically apathetic and can't feel emotions. He just tries to hide it by acting friendly. His backstory isn't tragic like some other demons', either, as he only became a demon for fun. Doma can be best described as an entity of pessimistic nihilism itself. Doma is a psychopathic, deranged, ruthless, misanthropic and manipulative nihilist who pretends to be outwardly friendly.
