The Yazidis are often regarded as devil worshipers because the deity they worship, Melek Taus, is equated by Muslims and middle eastern Christians with Satan. Melek Taus is an archangel like figure who was made Lord of the Earth by God. Because of this Yazidis believe that is Melek Taus, and not God, who must be worshiped. However they do not believe that Melek Taus is an evil being (unlike the Jewish/Christian/Muslim concept of Satan), as they believe that the source of all evil lies within the human heart.
