She furnishes us with no reason to believe that human life is to be respected. Nature, in her indifference, makes no distinction between good and evil. The belief in a supernatural source of evil is not necessary, men alone are quite capable of every wickedness. Non-cooperation with evil is as much a duty as is cooperation with good. One may say that evil does not exist for subjective man at all, that there exist only different conceptions of good.
Nobody ever does anything deliberately in the interests of evil, for the sake of evil.
Everybody acts in the interests of good, as he understands it. But everybody understands it in a different way. Consequently men drown, slay, and kill one another in the interests of good. The quiet conscience is an invention of the devil. It is easier to denature plutonium than to denature the evil spirit of man.
