It’s like a man in the trenches again: he doesn’t know any more why he should go on living, because if he escapes now he’ll only be caught later, but he goes on just the same, and even though he has the soul of a cockroach and has admitted as much to himself, give him a gun or a knife or even just his bare nails, and he’ll go on slaughtering and slaughtering, he’d slaughter a million men rather than stop and ask himself why.
