Did it? Even if you get actionable information from torture - a very big 'if' mind you - you're also going to get a bunch of specious bullshit that you'll waste time following up. If you arrive at the truth at all, which again is not likely, it will have been after being misled. You will be, by any objective measure, dumber for doing torture, even if you eventually arrive at the truth.

I try to act in such a way that I am made more intelligent, and I believe that governments probably should too (in particular the parts of government that we refer to as motherfucking intelligence agencies). But, to each, his own.
