Odd thing to fixate on, but yes. We ought to spend our energy on the terrible people still alive. Who cares what they do to the demon husks once they can’t hurt anyone anymore? Bury it with flowers and fireworks for all I care. Let’s focus on the suffering of the living.
Well believe it or not most people in the military are human beings, not bloodthirsty monsters that burn and mutilate bodies. Osama’s burial was done the way it was for pretty good reasons. Imagine the uproar and additional violence that would have happened if it came out that his body was treated like you say. It would have cost even more lives.
