A fruitless task - our sins are a bottomless pit, and there's lots more there they came from. But that's God's point, she'd doubtless argue - the fruitlessness. He's always liked futility. He thinks it's noble. She takes after Laura in that respect: the same tendency towards absolutism, the same refusal to compromise, the same scorn for the grosser human failings. To get away with that, you have to be beautiful. Otherwise it seems mere peevishness.
