There is no such thing as psychopathy; all humans are capable of empathy, Jewslave.
Humans are naturally tribalistic. We're made to care for ourselves first, followed by our family, then our extended family, then our community, then our race, and finally mankind as a whole. There is no variation in this programming between human individuals, and indeed this rule holds true even in the animal kingdom. It may be the most fundamental rule of life.
The reason I bring this up is that this aspect of human nature is in direct conflict with the desire of the elites to create one multicultural world society. The only way to do this is to counter our natural impulses in some way, and today this is done via social programming in school, mass media, government coercion, etc. Of course there will always be individuals who are stronger than this social programming - people who still prefer our inborn values over the constructed slave values of the Jews, and of course the social engineers will create methods for targeting these people. That's where the concept of a 'psychopath' comes from. As I said above, all humans have empathy - there are just some of us who restrict it to the deserving, or to those close to us, or to our race, etc. In popular usage these days, 'psychopath' indeed just means 'someone who failed to display empathy when demanded'.
Ironically, the true 'mental disorder' is in those who have empathy even for the undeserving, even for people that personally hate them and want them dead, and of course in you Jewslaves who've swallowed the Jewish lie of 'psychopathy' completely.
