Just a quick link to this paper, “The affective and cognitive empathic nature of the dark triad of personality,” which found evidence,

…indicating that individuals high on narcissism, primary psychopathy, and Machiavellianism experienced positive affect towards sad emotions

Also,

…primary psychopathy and Machiavellianism were associated with experiencing negative affect towards happy expressions.

If you’ve ever known a Narcissist, you will find them to grow increasingly depressing, as your relationship with them wears on. That depressing quality is a purposeful cognitive manipulation to make you sad, which in turn makes them happy. I’ve actually seen a male Narcisssist depress someone by focusing them on a sad aspect of their life. Once the target was sufficiently depressed, the Narcissist smiled, puffed out his chest, and raised his chin, as if simultaneously exceedingly pleased, and proud of his manipulation. It was surreal, and I would bet my stunned and confused facial expression as I watched, would have been funny as hell on tape.

This is why you cannot remain in contact with a Narcissist. They are like Terminator robots sent back in time specifically to screw up your happiness. That is a primary psychological drive in them. Even stranger, they know this about themselves, and revel in their bizarre urges – as well as your “stupidity” in being unable to figure out that this is what they are about.

Given that it is just accepted today that Narcissists are unusually common within politics, it makes you wonder if our leadership is actually fucking everything up on purpose, and deriving copious pleasure from all the misery they are producing. Could they actually be producing a collapse purposefully, just to watch all the little people get unhappy?

Strangely enough, the science would say that is likely exactly what is happening….
