I don't find them fascinating. I find them boring and dull, even when they are being what's considered charming. They don't have human minds, as if they are part of a general population. They have the consciousness of parasites who are merely seeking survival. I encountered them in my former work, and I unfortunately lived a case study of one in my family that was punctuated by the worst tragedy. I don't give a flying rip about their 'innerworkings'.
I came to believe years ago that they can only be identified and sorted and managed, "Managed" simply means educating about what they do, including the manipulative and insidious ways they enter relationships and gain control. The sociopath next door is often more dangerous than the hunting psychopath on the streets ( ex. killer of Morgan and Hannah), because they are entering the lives and stories of others in such obscured and masked ways.
There is, in my observation, almost a romanticized cultural narrative about the 'specialness' of what we're calling a 'psychopath'. We always hear about how much can be 'learned', but the truth seems to be so far, given the absence of any revelations no matter how many of them are 'studied', that they are all basically doing the same things on a continuum and through social portals.
Watts and people like him are the ones that care about the spotlight, so giving it to them via fascinated attentiveness is the provision of fuel. JMO
