" Even if a tamed wolf makes a good sheepdog, he will never understand how the sheep feel....You are most fortunate. For having been, as you thought, a coward, and helpless to fight - you know what that is like. You know what bitterness that feeling breeds - you know in your own heart what kind of evil it brings. And so you are most fit to fight it where it occurs. "

― Elizabeth Moon , The Deed of Paksenarrion (The Deed of Paksenarrion, #1-3)
