Desecrating enemy dead is not always a vengeful impulse, and in some cultures even has a religious component. At the same time, disgust at the desecration of the dead is not always a simple case of demanding respect for a fallen human being, but also carries religious implications, even on one’s journey in the afterlife.
“Virtually all religions have reverence for the dead. Different religions, especially the monotheistic faiths, don’t accept any desecration of their own dead, or the enemy’s dead,” said Carl Raschke, a religious studies professor at the University of Denver.
For example, Muslims believe that after death their bodies will slowly disintegrate, except the tailbone, which on the Day of Resurrection will regenerate into the complete human being. For that reason, most Muslims reject cremation because it destroys the tailbone, making resurrection impossible.
