In City Journal, Dalrymple traces the repeated attacks on the Soham child murderer Ian Huntley by fellow inmates, each of whom had committed appalling crimes of their own, and observes that even men diagnosed as psychopaths and devoid of moral sense are capable of moral outrage.
Though devoid of moral sense, they were capable of moral outrage. Russell reportedly shouted exultantly, “I’ve done it, I’ve done it!” after he attacked Huntley, to the reported applause of the other prisoners, many of whom would have been murderers themselves.
The capacity for moral outrage, of course, is not the same as a moral sense, let alone as morality itself.
