Dehumanization operates both as motive and as enacted physical performance

Evidence

Dehumanization is not confined to speech but can also be expressed in actions. Dehumanization that motivates terrorist actions should be distinguished from actions designed to dehumanize. The Nazis dehumanized their victims by stripping them of any personal identity and subjecting them to a subhuman level of existence. In the animalization that occurred in Abu Graib prison, guards forced detainees to wear dog leashes and rode on their backs as if they were beasts of burden. Islamic terrorists carried physical dehumanization to the ultimate extreme by beheadings and other atrocities. — Albert Bandura, Moral Disengagement, 2191
