Many that live deserve death. And some die that deserve life. Can you give that to them? Then be not too eager to deal out death in the name of justice, fearing for your own safety. Even the wise cannot see all ends. (Gandalf)
Frodo: I wish none of this had ever happened. Gandalf: So do all who live to see such times, but it is not for us to decide. All that is for you to decide is what to do with the time that is given to you.
