Our instincts draw from pretty far back in our biological origins as well. The notion of mimiclike predators is pretty damned ancient and likely a factor for very earliest common ancestry.
Psychopath is derived from Ancient Greek... And even besides that, laymen generally use the term to describe ASPD despite the two conditions not being entirely the same. Don't be obtuse.
The best non-DSM category for socio/psychopath I've come across is the lack of affective empathy, but intact cognitive empathy. (non-DSM because that's just symptom clusters not aetiologies, you quite literally need to have broken laws to be diagnosed with ASPD). Then you have a look at what skills are useful to have as a surgeon, like not flinching when you cut into people, and their character traits including their bedside manners, yep there's plenty of perfectly integrated psychopaths around. Same goes for pyromaniacs fire departments are full of them, you only ever hear about the ones who don't get the curve.
