As much as the term sociopath or psycopath are thrown around by people way too frequently, true sociopaths (as properly diagnosed by a mental health professional) comprise a very very small percentage of the population. I read the statistic a while ago and it’s like 1–2%, so it’s not as if you’ll see them popping out from under every bush and tree.
Someone like Ted Bundy would definitely be in this category. He was absolutely self centered, highly manipulative and was totally devoid of a conscience.
Obviously not every sociopath ends up being a serial killer. But all serial killers are sociopaths.
Another example would be Bernie Madoff. He particularly targeted charities and members of his own community (he was Jewish and mercilessly ripped off Jewish organizations and individuals).
Obviously he swindled plenty of others also, but he used his affinity with other Jewish folks to get them to trust him.
That is a coldhearted person. A true sociopath. He even manipulated his own kids, making them part of his schemes. No small wonder that one of his adult sons committed suicide once all the details came out. Realizing fully how little your own parent gave a damn about you is pretty devastating to process.
But since people like this comprise such a small percentage of the population, we would be well advised to not throw that term around as carelessly as is the current tendency.
Just because you fervently disagree with someone political views doesn’t automatically qualify him for sociopath status. Get a grip. And leave the diagnosing to the professionals best qualified to do it.
