Just in case someone doesn't, there are two diagnostic assertions in choro12's statement: low self-esteem, and sociopathy. This just goes to show that we as a society are dependent on psychiatric labels, even if we profess to hate them. We need them because they help us understand human behaviour. I'm not saying that this is good, and we should not try and develop an understanding of ourselves which goes beyond simple taxonomy, but that we should not be so hasty to disparage those who formalise and act on these categories, because we all do it, and we have always done so.
