“May we not say, perhaps, that the evil man is annihilated because he wished to be annihilated, or that he did not wish strongly enough to eternalize himself because he was evil? May we say that it is not believing in the other life which causes a man to be good, but rather that being good causes him believe in it? And what is being good and being evil? These states belong to the sphere of ethics, not of religion; or rather, does not the doing good though being evil pertain to ethics, and the being good [forgivable] though doing evil, to religion?”

Context: "When you stopped believing in God, did you stop believing in good and evil?"
"No. But I stopped believing there was a power of good and a power of evil that were outside us. And I came to believe that good and evil are names for what people do, not for what they are. All we can say is that this is a good deed, because it helps someone, or that's an evil one, because it hurts them. People are too complicated to have simple labels."

Context: He thought of the jungle, already regrowing around him to cover the scars they had created. He thought of the tiger, killing to eat. Was that evil? And ants? They killed. No, the jungle wasn't evil. It was indifferent. So, too, was the world. Evil, then, must be the negation of something man had added to the world. Ultimately, it was caring about something that made the world liable to evil. Caring. And then the caring gets torn asunder. Everybody dies, but not everybody cares.It occurred to Mellas that he could create the possibility of good or evil through caring. He could nullify the indifferent world. But in so doing he opened himself up to the pain of watching it get blown away. His killing that day would not have been evil if the dead soldiers hadn't been loved by mothers, sisters, friends, wives. Mellas understood that in destroying the fabric that linked those people, he had participated in evil, but this evil had hurt him as well. He also understood that his participation in evil, was a result of being human. Being human was the best he could do. Without man there would be no evil. But there was also no good, nothing moral built over the world of fact. Humans were responsible for it all. He laughed at the cosmic joke, but he felt heartsick.
