"What differentiates a sociopath who lives off the labors of others from one who occasionally robs convenience stores, or from one who is a contemporary robber baron - or what makes the difference between an ordinary bully and a sociopathic murderer - is nothing more than social status, drive, intellect, blood lust, or simple opportunity. What distinguishes all of these people from the rest of us is an utterly empty hole in the psyche, where there should be the most evolved of all humanizing functions." -- Martha Stout, Ph.D.
