Since we’re spitballing here, I don’t think he’s a sociopath. Narcissists can display a troubling lack of empathy but that doesn’t make them sociopaths. Trump seems to genuinely care about his kids, his wife, and everyone willing to lick his ass. He only attacks others when his sense of supremacy is threatened.
People are all the time claiming their ex-was a textbook narcissist or sociopath or whatever and then describe behavior that’s shitty or even abusive, but not narcissism per se. Likewise, sociopathology is likely more serious and intractable compared to NPD. Personality disorders can be really difficult to treat but they are in essence defined by patterns of behavior that are reinforced by their relationships (which yes, means treatment requires the people on the other side of the relationship to change in how they relate to the disordered person.) NPD is at its core a behavioral issue. Sociopathology is basically just, sorry, your brain is broken and you’re not really human. I was raised by a person diagnosed with BPD and a person most likely a sociopath based on the fact that he did things like blackmail his father using his father’s alleged murder history in order to extort a piece of land from him. He enjoyed killing animals, frequently waxed poetic about what a shame human conscience was, and he used people like kleenexes, including his teenaged daughter. There’s a world of difference.
Not that personality disorders are a walk in the park, or anything. But I think it really dilutes the ‘‘Trump is mentally ill’’ argument when people try to throw up any label that might stick. He’s a narcissist.
Notice how freaking subjective these criteria are. To an extent, all mental health disorders use subjective criteria, but given that personality disorders roughly translate (in the court of social opinion) into ‘‘you are a bad person’’ I think it’s especially relevant.
