Some philosophical problems on evil:
Satan and his demons exist. Satan and his demons are highly intelligent. Satan and his demons loose in the end.
If Satan is intelligent and knows he looses in the end, why does he keep trying? Isn’t he too smart for this? What is the purpose of pure evil for evil’s sake? Can’t we argue that most "evil"on earth is evil with a cause? By this I mean, even Hitler had a plan. A sick warped plan but a plan where a certain elect group of people would prosper.
Adultry, although is sinful and causes great pain, is most always justified in the eyes of the adultrous. He/She treats me
poorly. He/She doesn’t understand me. I have my needs…etc etc. Evil yes, but it is believed there is some good that comes from the adultry from the evil doer’s perspective. Companionship, warmth, understanding…things we call good. I am not endorsing adultry by any means, I am attempting to make a point. Point being that evil seems to come from ignorance and stupidity, not awareness and intelligence (which are attributes we attribute to the devil)
What is the devils purpose? If he has a purpose. Of what sense does evil for the sake of evil make from an intellectual point of view?
