I’ve encountered more than enough people who I’d call sociopaths, and for a while I read up to try to understand them better, and how to deal with them. I never had to use the term “psychopathic personality” before, and would go look it up before using that one. Sounds more severe and dangerous than most sociopaths.
One example of a case where someone’s behavior verged on the psychopathic, was calling the police to report their 16+ daughter was out driving without his permission. Still it wasn’t fully psychopathic – he was just willing to escalate to potentially do massive damage to his family, in order to get his way. (Calling police to ask them to arrest people, can and has gotten people killed.)
But I’m pretty sure that wouldn’t qualify for the actual “psychopathic personality” disorder – I expect that’s about people with almost no empathy, who routinely cause mayhem for others. (So yeah, Trump and Putin and Saddam Hussein and Charles Manson and so on.)
