My more simple definition of "Sociopath"

My definition would be "someone who has no empathy or feelings for other people's feelings or even whether they live or die."

So, a Sociopath doesn't consider the life or death of any human being but themselves as important in any of their actions. They can pretend to be caring but it is not genuine and is something that they do to "Trick people" into believing they are good people and not sociopathic.

We have all met people like this in different times in our lives and hopefully we survived those experiences without dying or being so traumatized we cannot function normally anymore.
