Such smug dispensation — as profoundly amoral as it is — provides us, on the cheap and at a safe distance, with a sense of moral worth. Or perhaps censuring from the bleachers enables us to feel superior to those less fortunate who are still captive to their primordial appetites. We prefer to cringe at the thought that others like to see proof of their killers' deaths, prefer to shoot rather than die capturing a mass murderer, and welcome a generic profile of those who wish to kill them en masse.
