Fun is the only reason to torture. But then facts do not matter when you are scared.
If I was in charge of intell you'd know where every person on the planet was and what they were doing every second of the day, mostly because I could do it not because I want to help. It is you who are anti-American more than most others. You like to see everything as black and white, America is about color. As I said, I am evil, I love seeing torture and analyzing the effects of it on human subjects. It's fun. I don't care about humans as a whole, but you neglect to admit that you don't either, you just care about revenge but won't admit it.
The effects of torture are well known, there have been many who have made a study of it, many who have also made it their career. You think those who administer torture care one bit about getting information then you are ignorant. It's interesting to see how quickly the various effects (hallucination being the most interesting, lobotomization can even occur in some cases which needs more study) occur within different subsets of the population. When one stops fearing everything and has felt enough pain themselves over long periods they tend to become the torturers, and for logical reasons.
One such subject began to hallucinate their own reincarnation. The study went on for hours while they actually relived their birth with a lot of strange fantasies added to it. When asked their name in this state they said a completely true but very altered version of their name. To the subject it was absolutely fact, though in reality it was far from it. Eventually their hear failed and the experiment ended. The technique used for the torture was the standard "noisy flashes" for 24 hours a day, 7 days. Then all we needed was a few pin pricks and their nerve endings felt almost ten times the pain. So after a few pricks of the needle their mind entered the state common with all torture victims. This was a military trained grunt, not worth much, but trained.
