I can't comment on Brady's mental health as I don't know enough or have the knowledge to decide. The fact remains that he indisputably murdered those children. You could argue that anyone committing such crimes must have a mental illness. However I think that once again the focus is on the perpetrator and not the victims. The public need to be protected from people like Brady, Sutcliffe etc and once their crimes are proven they should be confined for life no chance of parole. Capital punishment is not an option.
