Through all the darkness, through all the shame of which men are capable, the spirit of man will remain alive on this earth. It may sleep, but it will awaken. It may wear chains, but it will break through.
You'll come back, because yours is an error of knowledge, not a moral failure, not an act of surrender to evil, but only the last act of being victim to your own virtue. We'll wait for you and when you come back, you will have discovered that there need never be any conflict among your desires, nor so tragic a clash of values as the one you've borne so well.
