In Western culture, particularly North America, a lot of rules are descriptors for sociopathy: a general acceptance of lying as long as you win, an attitude of "me first," an attitude that what it looks like is more important than what it is. This makes it much easier for a sociopath to be camouflaged in our culture.
In northwest Alaska, kunlangeta "might be applied to a man who, for example, repeatedly lies and cheats and steals things and does not go hunting, and, when the other men are out of the village, takes sexual advantage of many women." The Inuits tacitly assume that kunlangeta is irremediable. And so, according to Murphy, the traditional Inuit approach to such a man was to insist he go hunting, and then, in the absence of witnesses, push him off the edge of the ice.
Sociopaths are not usually physically violent. A typical sociopath never kills anybody and doesn't look like Charles Manson - they look like you and me and everybody else. You're not looking for someone who's recognizably evil or scary-looking, but rather someone who looks normal. Another lynchpin is dishonesty. Lying for the sake of lying. Lying just to see whether you can trick people. And sometimes telling larger lies to get larger effects.
Someone, or some group in George W. Bush administration, took 300 million people to war against their will, based on a very giant lie. Combined with the notion of winning, that is, to me, a horrendously scary situation.
