You do not have to be a murder to be a psychopath.
Psychopathy is traditionally a personality disorder characterized by persistent antisocial behavior, impaired empathy and remorse, and bold, disinhibited, and egotistical traits.
It sounds like the MC to me. Sleep rapes every woman he can. Blackmails a woman for refusing his advances. Tells Caroline he loves her as he continues to satisfy his carnal lust for every woman who he meets. Even though she tells him how delicate her mental state is. Fucks over Bob so he can wet his dick in more ways than one. Gets some guy murdered.
And don't get me started on that POS Linda
