The power that evil men have in this world does not extend to damning us. It is a mistake to grant them that power. No earthly goal being sought through hellish evil is worth the candle, and no merit or worth of any kind can survive the procedure. If you justify torture as expedient you will soon find murder even more expedient. If you find those expedient directed at evil enemies you will find it even more expedient to not need to bother about being sure of that. We know where that whole process goes, and it goes straight to hell.
The whole idea that the secret of power lies in evil or that wars can be won in torture chambers, is false from top to bottom. Those attempting it do not deserve "saving" and their achieving their ends is not choiceworthy itself. Nothing any of you say or do will ever force any of us to support torture. Instead you simply make yourself an enemy of all mankind. (A group that can be as restricted as you please; you can leave it at any time to enlist in the legions of hell).
“No, there are no exceptions.”
In that case, it’s a good thing that waterboarding isn’t torture.
Now you can go to sleep every night with a clear conscience.
