I guess there's something thrilling/dangerous about an ultimate "bad boy" like this. Look at all the weirdo women that fell in love with Charles Manson. Does knowing his slasher personality add to the allure? I can see a sort of Sweeney Todd Demon Barber of Fleet Street sort of appeal to this guy. I can also see him rotting in prison for 25-to-life but I doubt we'll see that.
