It is in the nature of humans to depict evil as ugly and good as beautiful. The devil has to be ugly because it is evil; at least that is the notion. I believe that I have read accounts of Lucifer as being the most beautiful of the angels before he broke with God. As I remember his beauty was one of the reasons he thought he could challenge God. I don’t remember that his appearance was changed when he was cast out.
Beauty attracts people that ugliness repels people; that’s the way we’re built. I would pose these questions. Have you ever been in the company of a person that would be considered very pretty long enough to find out that their personality made them hard to be around? At that time did they even seem physically less attractive?
Also, have you experienced the reverse where a person that you would put near the bottom of the attractiveness scale started to look better to you when you found out what a wonderful human being they were? I think that our visual perception of people can change as we understand their nature.
I don’t want to leave the impression that I think all good looking people have bad personalities. That notion is no truer than the reverse notion. What I can say is that attractive people have a great advantage in just about any social interaction. I have seen many experiments where an attractive person would stand on a corner a drop a bunch of papers (the gender of the attractive person seems irrelevant) and in a minute there will be one or more people there to help gather the papers. If a less attractive person drops the papers people step over them and keep on going. We seem to need the approval of attractive people and regard less attractive people as less valuable.
Let’s face it guys, if this lady dropped papers on a corner, we would take a cross town bus to get there to help her pick them up.
Any entity as evil as the devil must be ugly in order for them to fit the mode even though there seems to be writings to the contrary. Is it any wonder why people of both genders get duped and lose all of their money to attractive scam artists?
In one of the first science fiction stories I wrote, I postulate that appearance will be the last great discriminator. After we get over all of our other prejudices, we will still treat people differently based on their appearance. It is the one discriminator that allows us to be both a victim and a perpetrator.
