I used to think it was overpopulation many, many years ago. No more. I recognize that overpopulation is what weakens the social immune system to permit opportunistic infections by psychopaths. The pathogen itself is human.
The psychopath is not really a human. It's a mimic. It doesn't feel any emotions normal to mammals. It is driven by the same emotions that reptiles have. All the warm blooded stuff is missing.
When I began to see this phenomenon everyday in the workplace, so many things became crystal clear to me. People I had previously thought to be aggressive, assertive or professional I now realized were no such thing. They were something else altogether.
The psychopath and sociopath wreck every single environment you put them into. After they have wrecked it, bankrupted it or destroyed it, they make you feel grateful for knowing them when they leave. It is a combination of Jason and Rasputin blended with pure asshole.
I was talking about promotion in the Army in a couple posts prior. It was only twenty years after the fact I had a good think about it and realized that the people promoted most quickly in the military were the same people with drug and alcohol problems, people who failed their aptitude tests and avocational tests, people who failed their physical tests and people who missed formation, disobeyed orders, broke the rules, got into legal trouble with civilian law enforcement, went AWOL, couldn't shoot, couldn't hike and couldn't perform even the smallest tasks without failing miserably. I knew subconsciously after a couple months in the Army these people would be rapidly promoted up through the ranks - by their fellow psychopaths running defense for them higher up.
These sorts of people always had supreme levels of confidence and esteem. I would describe it as an ongoing state of euphoric joy at their own wonderfulness. They dominated every conversation, assumed every discussion was about them and took turns celebrating their own incredibleness. Nothing about their worldview was realistic or anything but maladjusted and it had a way of infecting everyone else with the same failed misunderstandings. This eventually led to unit-wide failures in the field, failures to pass inspections, failure to perform to standards, failure at almost everything. Before you knew it, everyone else was failing and now they had that same cocky, self-assured air about them as everything got progressively worse. Sometimes a high ranking outsider would look in on the organization and be absolutely baffled at just how far it had all run off the rails. I always knew that these objective views were endangered, destined to be replaced by other pod people leaders backed by psychopaths. It was exactly like watching the entire installation be taken over by alien body snatchers. The next thing you knew, the one decent lieutenant or captain you had turned to for some anchor had vanished and in his place was one of these fingers-snapping, cool stepping bullsh*t artists in his position, discarding all existing standards.
All it takes is for one to install himself in an authority position and they will chain each other up and replace competent people there now. Before you know it, they will be running the whole show and turning all healthy standards completely upside down. This is the way they roll. This has been working for them for tens of thousands of years.
Idiots are easy to keep perpetually distracted while you rob the nation blind.
The difference is that 40,000 years ago even if you were running the tribe of spearchuckers you weren't much of anything but in charge of a bunch of muddy savages. When the Neanderthal was absorbed, this entire class of parasites was now sucking blood from a species that was on it's way to inventing nuclear weapons. It is Amud genius that really gave these monsters something to highjack. If you install yourself and your gang of thugs as king coconut over a tribe which has nuclear weapons and death star satellites in orbit, you've really pulled something off.
The psychopath-sociopath was an existing disease of large tribe Sapiens. He only acquired the potential to become a supervillain when the Neanderthal bastards were born.
