Psychopathy is a personality disorder characterized by persistent antisocial behavior, impaired empathy and remorse, and bold, disinhibited, and egotistical traits.
“I think all our society is run by insane people for insane objectives... I think we’re being run by maniacs for maniacal means. If anybody can put on paper what our government and the American government and the Russian... Chinese... what they are actually trying to do, and what they think they’re doing, I’d be very pleased to know what they think they’re doing. I think they’re all insane. But I’m liable to be put away as insane for expressing that. That’s what’s insane about it.” - John Lennon
