(Personally I think torture is always wrong, I just want to make sure the legal issue is clear.)
In that comment, I said torture was unacceptable and more so when it was done in my name.
I have since wavered on this as I've considered some proposed hypotheticals. I've decided, at least for now, that it may not always be wrong but that it is always abhorrent.
Hypothetically, such a situation could exist where it is the right choice but it is still reprehensible. The whole WMD thing and saving a city? Yeah, I guess it's the right choice but it's still abhorrent. If I had every reason to believe the information could be extracted, I'd do the torturing myself.
In the end, I'd hope that I'd be more unhappy that I was forced to do so than I was unhappy that I did so. I imagine it would bother me for the rest of my life, but I'd accept that burden.
