Is power that—an emptiness? - Ursula K. Le Guin

War as a moral metaphor is limited, limiting, and dangerous. By reducing the choices of action to 'a war against' whatever-it-is, you divide the world into Me or Us (good) and Them or It (bad) and reduce the ethical complexity and moral richness of our life to Yes/No, On/Off. This is puerile, misleading, and degrading. In stories, it evades any solution but violence and offers the reader mere infantile reassurance. All too often the heroes of such fantasies behave exactly as the villains do, acting with mindless violence, but the hero is on the “right” side and therefore will win. Right makes might.

A dark hand had let go its lifelong hold upon her heart. But she did not feel joy, as she had in the mountains. She put her head down in her arms and cried, and her cheeks were salt and wet. She cried for the waste of her years in bondage to a useless evil. She wept in pain, because she was free.
What she had begun to learn was the weight of liberty. Freedom is a heavy load, a great and strange burden for the spirit to undertake. It is not easy. It is not a gift given, but a choice made, and the choice may be a hard one. The road goes upward towards the light; but the laden traveler may never reach the end of it.

To know there is a choice is to have to make the choice: change or stay: river or rock.
