" Human beings naturally hate to torture other human beings, and Americans are no different. Many of the soldiers were doing the job reluctantly, and were very happy when they were ordered to stop. Of course there are sick people everywhere in the world who enjoy seeing other people suffering, but generally human beings make use of torture when they get chaotic and confused. And Americans certainly got chaotic, vengeful, and confused, after the September 11, 2001 terrorist attacks. "
