Regarding State torture, it's notable that Christ clearly inferred that there is a separation between those Governments that are led by his creation and the Heavenly Government that He is the King of. When Christ was shown a coin with Caesars likeness on it and was asked about whether or not taxes should be paid, he responded,
"Render unto Caesar the things that are Caesars and unto God the things that are God". Right or wrong, it's a function of the people's Government, not the Government which Christ is the head of.
I was reading this morning from Luke (a book in the New Testament

) and in Chapter 6 it states that we are to
"love our enemies" and pray for them. In light of that, I'm not sure how a Christian can reconcile condoning or participating in torture.
I've never prayed for the terrorists. I asked my wife, who spends more time in devotions than I do if she had, and she stated that she had not. Yet, it's a command from Christ rather than a suggestion.
(Food for thought...)
