Yes to everything HK said.
I might go further and say that even psychopaths are unfairly dehumanized. It has been established that the population of criminals and persons who otherwise hurt others is enriched for psychopathy, but it does not follow that everyone on the psychopathy spectrum is harmful to either individuals or society at large. I suspect that the majority of them go unremarked, in relatively ordinary, socially-acceptable roles (depending on your view of surgeons, corporate CEOs, Wall Street, and politicians, I suppose).
A diagnosis or constellation of traits describes only a very small slice of any human being's existence and experience.
