There are some practical reasons to be cautious about using torture
1. We might wind up torturing innocent people
2. If we get caught, there is a large price to be paid - retaliation, loss of support for the war, reduced ability to get international cooperation.
Additionally, I am a Christian and I know torture of a helpless person is wrong but there are sufficient reasons to be careful about it without getting into morality.
Now personally, if someone was holding my wife hostage, I'd be willing to do whatever was needed. But that's why we have rules rather than allowing our feelings to make the rules.
You can't play with Amnesty International rules against Islamic terrorists.
What you do is kill every one of them you can find. Leave alive only the ones that can provide useful information that will save American and Iraqi lives. Get that information any way necessary.
It's always desirable to win "clean" when you can afford it. If we can't, then win "dirty" if that is what it takes.
That's the way I feel about it.
