I can understand being totally ruthless and unscrupulous if you are so fanatically committed to a particular philosophy or ideology that any action is justified if it furthers that idea.

But I get the impression these guys would just as easily ply their trade and work for the other side. They have no commitment, no dedication, they are totally mercenary. This is what I find so disturbing about the business mentality. All that matters to them is their financial success, and that success is not merely a means of providing them with security and comfort, which (after all) we are all concerned about. For them it is their means of self actualization, this is how they define themselves as human beings. This is how they keep score. And I suspect that they have nothing but absolute contempt for anyone else unless they share that same conviction and motivation.

This is pathology. Its like a soldier who does not fight for his country, or because he is honor bound and sworn to duty, but only fights because he enjoys killing and humiliating and torturing others.
