Oliver Queen

If you will not fight for right when you can easily win without bloodshed; if you will not fight when your victory will be sure and not too costly; you may come to the moment when you will have to fight with all odds against you, and only a precarious chance of survival. There may be even a worse fate. You may have to fight when there is no hope of victory, because it is better to perish than to live as slaves.

--Winston Churchill
