Not to change the subject, but I've wondered that same thing about psychopathy as well. A detachment from one's conscience. Dissociation brought on by a lessening of need for bonding with others in modern society. A dehumanization process that is an unfortunate consequence of technological advancement.
Buzzkillington! Take that kinda talk somewhere else. This is a cool thread, don't you go foul it up with psychopaths. That's what the entire rest of GSUS is for.
I am only half kidding. You could be onto something with your idea. It seems possible, but it is depressing to think about it.
