I'm not sure why people seem to have so much trouble with personification, since we apply it so easily.
Personification is a
literary technique in which inanimate objects or abstract ideas are endowed with human self-awareness. IOW, human thoughts, actions, perceptions and emotions are attributed to the inanimate object or abstract idea.
But there is another aspect of personification that applies to the use of Satan.
Taking a human behavior or a force of nature and representing it as a person is also personification.
Wisdom is personified in the Bible. Jealousy is another that is personified often.
We can't personify people because they are already endowed with human self-awareness.
Understand?
