I remember having terrible nightmares during the trial, feeling that the police were misunderstanding things badly because they insisted that Sutcliffe had a moral stand. To me it was clear his crimes expressed a simple, virulent loathing of the female which did not need fancy explanations like those arrived at by the police. The thing is that most people in the book are not what ordinary people would describe as outcasts; they are ordinary men. That was why it was important to end up with the Ripper. Because what is important about him is that he is not different; it's only a question of degree. I don't go along with the idea that all men are rapists or that they are the product of Original Sin, rather that we have a culture which supports and encourages misogyny and what we have to face is that a sizeable number of men hold very strange and perverted views about women.
