With respect. If someone can hold down a job, still has capacity to reason and be crafty enough to fool psychiatrists, they are responsible for what they do. His wife didn't appear to have a problem with what he did, just described as a cold uncommunicative woman, but she remarried,yet still lives alone in the house she had shared with Sutcliffe. That's weird.
My sympathy is with these victims families. We don't have the death penalty so many serious offenders are given parole and commit the same crime so another grieving family pays the cost. Thankfully not him.Whatever happened to him is nothing, he grew old and fat in prison, his victims most of them barely out of their teens. At least we are not funding him any more.
