Deranged individuals came first. If you research psychopaths, you'll find that they have certain areas of their brains that don't function properly. This makes them paranoid, self-centered, delusional control freaks. It's genetic and therefore hereditary and can't be altered via conditioning. There is a niche for psychopaths, but it isn't in politics or any place where they can be in positions of authority backed by power administrations. Some of the best surgeons are psychopathic. They have no compassion for their patient and therefore forge ahead to cut them open and do what they can to repair whatever it is that needs repairing. But they are also self-centered and often brilliant and in need of praise, so they do the best job they can possibly do and that often results in success for them and for the patient (as an aside). If the patient happens to die, the surgeon doesn't have the capacity to feel much remorse but feels he did his best and that's enough. He can go on to cut open the next "body" and do what needs to be done without worry.
Unfortunately, some psychopaths have control of armies and world financial institutions. This is not a good thing for us little people.
Truth be known, I have a few traits of psychopathology. I'm pretty narcissistic and desire praise and acknowledgement. But I am not paranoid, nor do I want to be in any position of control, other than in complete control of my own actions. If I didn't have these psychopathic traits, no doubt I would not bother writing or posting my opinions. Good or bad? It is what it is.
Though I may be a psychopath, I am not schizophrenic and neither am I. ;-)
Fascinating...lol...
