I think we should bear in mind that the idea that torture isn't moral isn't as universal or as long-held as some people seem to assume. One example I like to bring up is the old English legal system from the Middle Ages: torture was considered a reasonable deterrent, providing it did not impair your ability to do your job, whereas imprisonment was considered inhumane. The reason being that given the social system of the time, if a man was imprisoned and was not earning wages, his family would starve when they had not committed any crime themselves, whereas torture would be a painful deterrent to him without hurting them. Obviously that kind of idea doesn't apply any more, but I use it as an example to show how attitudes can be more relative than people think.
