" The Jungian doctrine of the shadow and the notion that evil is the reverse of good are aimed at denying the reality of evil. But evil is real. It is not innate but acquired, and it is never the reverse of good but rather its destroyer. Shakespeare was aware of this. He saw and showed the origins of evil but never tried to relativize evil by using psychological explanations, as is done in psychoanalysis, for instance. Richard III, Macbeth, and some of his other characters are evil because they are destructive, even when we know why they have become so. Our knowledge cannot alter them. They can change only if they sense, not merely intellectually but with their feelings, how they have been turned into evil people. "
