I know I'm late to the discussion; I just saw this thread.
My grandfather was a sociopath if ever there was one, and while it made growing up a little harder on me, it also makes it easier to spot them.
Splitting hairs perhaps, but I sometimes wonder if there's more of it, or if instead people used to hide it or attempt to work around it more? It's been getting easier and easier to find other people that are really similar to yourself, and I think that's a really mixed blessing when it comes to ideas about personal accountability and license. I'm 45, and I've been watching the masks and the gloves coming off more and more as I age.
