““It makes absolutely no difference in the scheme of things whether all but a handful of people live or die. No more than the importance of a single flower, or blade of grass, or vegetable, or bird. It would make no difference if those men who held that ancient pass or that equally ancient fort had, instead, died of disease or old age or in a saloon fight. But it made a difference that they died where they did. It mattered. It justified their whole existence.””
