and that probably explains a lot about the world.
however, i wouldnt call people affected by psychopathy a "subspecies", and i strongly doubt they have any extra psychopathy-sensing special abilities like sight or smell. that is crossing over into wild conspiracy territory.
(its also important to note that there are lots of people who have all the typical traits of psychopathy, but dont act like what people would call "psycho". there is way more nuance to psychopathy than usually portrayed in media or whatever)
