I don't think the world is black and white like that.
Hypothetical: someone kidnaps a child and the police capture someone who definitely knows where the child is. The child's life is at risk. If the parent were to beat up (torture) the person to gain knowledge, you'd assume the parent "likes" torturing people? I wouldn't.
I was disagreeing with the idea that a hypothetical torturer necessarily expects it to work (and giving an example of an alternate theory for why they might be a torturer), not saying that all torturers like torturing.
