Will the Real Sociopath Please Stand Up?

Sociopath, psychopath, person with anti-social personality disorder diagnosis...it isn't a simple task to find agreement about these descriptions. Are they synonymous or distinct from one another?

Aside from the individual who as a child was "fascinated by fire" and actually started fires, tortured small animals then graduated to a sadistic serial killer of their fellow human, do any of these terms describe someone who is basically bereft of a conscience or failed to physiologically develop whatever part of the brain that provides the ability to empathize or feel guilt when it would be appropriate? That's the person I'd like to understand better.

To that end, here is short "favorites" list (mine) of links that provide different perspectives on the subject:

Meet the New Occupant

If you found yourself here by way of a URL link from another site, I wanted to make provisions for those expecting a different blog author.

This was, at one time in a not very distant past, the blog name for an unknown person self-described as having the condition of anti-social personality disorder (pyschopathy).

If you were expecting to learn something interesting about this psychological phenomenon, you may be disappointed.

However, here is a link back to where I discovered that this blog name was no longer occupied by its' original owner.
