purification is accomplished by an act of expulsion. Something vile on the “inside” is forced “out.” Scapegoating is the religious and social analogue of the vomit response in disgust, a violent rejection of a contaminant from the body. This is the same dynamic seen with the expulsion of monsters from the community. Monsters and their ilk, representing degradation and defilement, must be expelled from the community to secure a “cleansing.”
