Googled it up, there’s no DSM for psychopath, instead, the psychiatrists would label an individual as having “Antisocial personality disorder”, rather vague, though a psychopath, “A "psychopath" is someone whose hurtful actions toward others tend to reflect calculation, manipulation and cunning; they also tend not to feel emotion and mimic (rather than experience) empathy for others.”
An example, a psychopath CEO has no issues with doing layoffs, as they can’t empathize with the employees being laid off, however, what they’re doing, reducing overhead, is in the better interest of the shareholders. So, I’m guessing there’s a degree to the psychopath. Some are more goal orientation, don’t care about busting rules/hurting to make the goals. And some went further, enjoyed the busting/hurt, and therefore enjoy the means as well as the goals. Not absolutely certain without becoming a psychopath myself.
