"Psychopath" is a description, it's not some immutable characteristic like your sex, race, or genetics. Scientists claim that there are "psychopathic" brains, but that's bunk because "science" doesn't really understand the brain all that much. Somebody could have an above average tendency to want to hurt people that piss them off, but it doesn't matter. Everybody has urges, everybody has different tendencies. One can have urges, doesn't mean you have to give in to them.
