El Wikipedia tiene la siguiente información acerca de este punto de código:
A devil is the personification of evil as it is conceived in various cultures and religious traditions. It is seen as the objectification of a hostile and destructive force. Jeffrey Burton Russell states that the different conceptions of the devil can be summed up as 1) a principle of evil independent from God, 2) an aspect of God, 3) a created being turning evil (a fallen angel), and 4) a symbol of human evil.: 23
Each tradition, culture, and religion with a devil in its mythos offers a different lens on manifestations of evil. The history of these perspectives intertwines with theology, mythology, psychiatry, art, and literature, developing independently within each of the traditions. It occurs historically in many contexts and cultures, and is given many different names—Satan, Lucifer, Beelzebub, Mephistopheles, Iblis—and attributes: it is portrayed as blue, black, or red; it is portrayed as having horns on its head, and without horns, and so on.
