Is torture wrong? Yea, you know what it is, but we aren't picking up random people and flying them to Cuba to play "Hostel". Intelligence studies propaganda videos online, surveillance, phone records, photos of camps to decipher who is important. They don't take in a low level recruit from a raided camp and torture him, they already know he has no Intel on the whereabouts or objectives of the higher ups. The guys in Cuba are there for doing some pretty bad stuff. These aren't hotdog vendors that got picked up in a dope raid by mistake from the city police, that's not how it works on this level.
That's the point that a lot of these "no torture" softies miss. It's not like the CIA is abducting taxi drivers from their homes in the middle of the night and shipping them off to Gitmo, HOPING that they have the right guy. If you have made it to Guantanamo Bay, it's because you've been up to some pretty awful shenanigans.
And in a perfect scenario, waterboarding would be the least of these scumbags' worries.
