Does evil, as we conceive it to be when we do not do it, exist? Does not the evil that we do seem to be something simple and natural which compels us? Is not evil analogous to illusion? When we are the victims of an illusion we do not feel it to be an illusion but a reality. It is the same perhaps with evil. Evil when we are in its power is not felt as evil but as a necessity, or even a duty.
