Evil is a word we use to describe the absence of Good, just as we use the word darkness to describe the absence of Light or death to describe the absence of Life. Both evil and darkness can only be understood in relation to Light and Good; they do not have any actual existence. I am Light and I am Good. I am Love and there is no darkness in me. Light and Good actually exist. So, removing yourself from me will plunge you into darkness.
An enemy that is pure evil? Right or wrong are not what separates us and our enemies. It's our different standpoints, our perspectives that separate us. Both sides blame one another. There's no good or bad side. Just two sides holding different views.
I don't believe in playing down to children, either in life or in motion pictures. I didn't treat my own youngsters like fragile flowers, and I think no parent should. Children are people, and they should have to reach to learn about things, to understand things, just as adults have to reach if they want to grow in mental stature. Life is composed of lights and shadows, and we would be untruthful, insincere, and saccharine if we tried to pretend there were no shadows. Most things are good, and they are the strongest things; but there are evil things too, and you are not doing a child a favor by trying to shield him from reality. The important thing is to teach a child that good can always triumph over evil, and that is what our pictures attempt to do.
