Keith Parsons is mad:
I am angry. Very angry. We know that Islamic fanatics are mad dogs whose very humanity has been consumed by their devotion to a rabid religion. We have seen them massacre whole communities of innocent people for no reason other than religious bigotry. We have seen them kidnap hundreds of girls and young women then sneeringly taunt the loved ones of their victims. We have seen them murder and mutilate other girls for the crime of seeking an education.
Now, I happen to agree with him. But Parsons has a problem. He's a militant atheist. There is no eschatological judgment. Terrorists never get their comeuppance. Death is the great leveler. Both good guys and bad guys share a common oblivion. Irreparable harms or wrongs in this life are never rectified, for there is no afterlife, no heaven or hell.
Even for the handful of terrorists who are captured and punished, their crimes are so far in excess of what human justice can requite that it's pitiful.
