The remedy for an absence is a presence. Evil is an absence and, therefore, it cannot be healed with an absence. By hating evil, or one who is engaged in evil, you contribute to the absence of Light and not to its presence. Hatred of evil does not diminish evil, it increases it. The absence of Light causes the personality to suffer. There is pain. When you hate, you bring that suffering upon yourself. Hatred of evil affects the one who hates. It makes him or her a hateful person, a person who also has absented himself or herself from Light.
