Some have pointed out that one can believe that something is "God's will" but it's quite another thing to impose that view on others. In the recent case of Richard Mourdock's statement about pregnancies due to rape, there seems to be little doubt that this person could envision sending a SWAT team into a doctor's office to arrest a woman who is trying to have a rapist's fetus aborted. I wish Democratic candidates running against such individuals would point this out, preferably during debates with them, but there is another sinister aspect to this way of thinking.
If we "deconstruct" this line of thought, we see that someone is telling us that the most vile criminal acts are God's will, and that the results of those acts should be embraced as such. This idea, though I'm not sure if these kinds of people are intelligent enough to realize it, can be used to circumvent logic and reason, replacing them with ludicrous justifications. If a rape is God's will, why wasn't Lincoln's assassination, or Hurricane Katrina, or AIDS, or Hitler's genocidal actions, or Stalin's purges, or anything you would like to be, God's will? If a protester punched Mourdock in the face, was that God's will? If so, does it mean that he's wrong? Since he can't imagine that he could be wrong (in his mind, presumably), then it must mean God is testing him, and that he should be even more firm in his convictions, one assumes. The insanity just "snowballs."
And then there are the more mundane justifications: "Yes, my father was rich, and I became a corporate raider and was responsible for closing down American companies and outsourcing good jobs to China and India, but that must have been God's will, right?" In short, for such people, everything is simple, and "anything goes," so long as it is consistent with his/her theology or world view. This is at least one major reason for the need of the "separation of Church and State," so at least we can thank him for providing such a clear example. Thus, not only is it important to call such people out on their desire to impose these kinds of notions on everyone else, but I think it's also crucial to point out that anyone can create such claims: nothing is required other than a desire to support the unsupportable. And let us not forget what many of those who actually committed such horrible crimes (or who were tortured into making false confessions) have told us over the centuries: "the Devil made me do it."
