Psychopaths fill a niche. In a prosocial and empathic world, there is an advantage for a group to act both antisocially and without affective empathy. If this were business, we would celebrate the ingenuity of such a group to find such a niche and to capitalize upon it. However, this is not business, this is life, and as such, neurotypicals lose their collective shit when faced with someone who can act while the rest of the crowd stands still. We acknowledge the annoyances of the mosquito with its bloodsucking ways, but we do not eradicate it for ecosystems are calibrated to survive with its existence. The same train of thought should be applied to the realm of psychopathy. I will concede that the unchecked psychopath may be an irritant to those neurotypicals around him, however I do believe that society could not function for long without his existence.
