The "no religion" crowd sees a moral equivalency between intentionally slaughtering civilians in the most barbaric ways imaginable and harshly interrogating suspected terrorists to prevent future attacks? Well that's just shocking.
I don't think they see it that way at all. I'm in the "religious" crowd that thinks torture is wrong, though, so I can't speak for them. The way I see it, there will always be awful people in the world, and as a religious person, I should forgive them and move on with my life. Two wrongs don't make a right, an eye for an eye leaves the whole world blind, etc. It's ok for others to do the wrong thing, but it's not ok for me to do that, and I'd rather my government not do the wrong thing, either.
