A person is a unique creation.
He can create himself too.
If he becomes a torturer, he has created a monster.
Very slippery slope.
On this we agree.
But it is demonstrative of the classic moral delimna: Is it OK to sacrifice a few to save the many?
It was existentially essential post 911 to determine if there were any other attacks coming and whether WMD attacks were on the near horizon.
The men who answered those questions for the nation bear a great moral burden, then and now.
The same could be said for those who dropped the bomb in WWII.
