I think if you take the view of modern genetics, admittedly I'm a layman on this topic, this is an often useless, antiquated (nature vs nurture) reductive trope. Despite what genetics may code for, our actions are a sum of intrinsic and extrinsic factors. Genetics being one, epigenetics potentially another as well as upbringing, culture, diet and multitudes of other factors. Someone with psychopathy may produce positive societal results even to the benefit of himself sometimes if conditions favor such behavior although could very well go wrong given another upbringing. I think the implications of labeling these behaviors as "dark" can be a bit too reductionist and can turn into a literal witchhunt if we're not careful although they do provide some sort of utility in patterning human behavior.
