Let me tell you of vengeance. Gods are vain and fickle, but vengeance is an honest thing born of man alone. It is as natural as breathing and as old as time, and it overrides all--even duty to your lord. It does so because it is itself a duty, a holy moral duty, and anything can be forgiven in its name--so long as you are prepared to give everything for it. This is being samurai. Do you understand?
