Literary Evil
I was thinking of two definitions of Evil that inform our culture.
One that comes up is the idea of Evil as the hardening of the heart. In Genesis, it is said "God hardened his [Pharoah's] heart." The idea here is that the Pharoah could no longer feel. He was only concerned with the immortality of his own culture which he found himself to be a symbol of. He would rape, kill, destroy, and enslave other cultures so that momuments of immortality to Pharoahs would be built to last forever. A person in a dominant position of authority who acts in this manner is considered evil and his punishment is that the very things that he did to others come back to him through some supernatural force.
The other idea of evil is the image of the a plant or flower in a garden that has gone wild. This idea was popularized and developed to its fullest by Shakespeare. The English love for gardening is perhaps an affect of Shakespeare's elegant and mature development of the gardening theme.
Shakespearean heros or antagonists like Macbeth, Iago, Hamlet, and others are characters who have too much of one characteristic: vanity, envy, hesitation, or greed. They let this one characteristic grow wild and kill off all the other characteristics that need nurturing and maturing. On a subjective level, they suffer from obsessions with power, guilt which produces emanations of ghosts, etc.
Of course, in characters like Nebuchadnezzar, a mighty Babylonian King who becomes a beast, both aspects of these ideas about evil come out.
I was simply wondering if anyone else found examples of "evil" which informed our decisions to go to war or to leave things be.
