What is the difference between a Psychopath and a Sociopath?
In my opinion they can almost be interchangeable. A Psychopath will get pleasure out of physically hurting someone or even killing them. To a Psychopath there would be nothing wrong with doing such things. A Sociopath knows that there is a right and a wrong, although not quite the same as what a non-Sociopath would perceive.
Sociopaths are one of few types of Human who can control, take advantage of, abuse a Narcissist and have that Narcissist begging for more. A Sociopath has no need for Narcissistic Supply and can play the Narcissist by becoming their Highly Valued Source of Narcissistic Supply. They can squeeze every last cent out a Narcissist, as long as they are deemed to be a highly valued Source of Narcissistic Supply.
