These examples raise the question of what is evil. It is a lot easier to give examples of it than to define it. Extrapolating a definition from these examples and, even more, from the feeling that caused me to choose these examples, I would define evil as that which is deliberately calculated to cause despair. That would cover the exact quality in each of my cases that makes them as horrible as they are. In The Exorcist, the book, Father Merrin says, "I think the demon's target is not the possessed; it is us ... the observers ... every person in this house. And I think - I think humanity, Damien: to see ourselves as ultimately bestial; as ultimately vile and putrescent; without dignity; ugly; unworthy. And there lies the heart of it, perhaps: in unworthiness. For I think belief in God is not a matter of reason at all; I think it finally is a matter of love; of accepting the possibility that God could love us. ..." And from Michelle Remembers, "Now she saw a nice-looking man, a good man who had made a mistake or come to a the end of his rope. He was wearing a baggy sweater and he was shuffling along a street, oblivious to the autumn leaves and the glowing street lamps. The man went to a telephone booth on the corner, and dialed a number. The telephone rang and rang, but no one answered. He tried another number, and another. No answer there either. He leaned his head against the glass side of the booth for a moment, and then he walked away into the night. He had given up. It was too late."
Many of my examples depict things that are flagrantly unnatural (the spider walk, the snake woman), sudden reversals of mood (the evil chorus, the snake woman), willful acts of malice (the chorus member inverting the crucifix). The very universe, life, itself, suddenly makes no sense. If the universe, itself, turns crazy, turns against us and against life, what wholeness and integration do we have left? We lose our sense of harmony with the universe, our sense that perfection and beauty are the true order of reality. We become disconnected from it and, in turn, disconnected within ourselves.
A final characteristic of evil is the death of the soul which is the death of love. What is left when someone turns against hir very love, whatever that love had been directed to? To turn against one's love is to turn against one's own Self. It is soul-suicide. We all know in our hearts what we love and that it is sacred. Evil isn't a particular act. That's too easy. Evil can be different for everyone. What makes it evil is the relationship of the act with the soul of the actor. It is, after all, in the heart and soul that good and evil reside.
