I want him saved.
I want him to spend the rest of his life in prison.
A quick death is not what he deserves.
I want him to live the rest of his life alone, miserable and scared shitless about being attacked by fellow inmates.
I want him to feel some semblance of the fear he inflicted on his three victims every single minute for the rest of his existence.
I want him to never experience any joy or even contentment for the rest of his life.
I want him to get no pleasure from anything. Reading, watching television, playing a board game. Anything.
I want him to be fed shit flavoured protein shakes to meet his nutritional needs.
I want him medicated so he can't get an erection and wank off ever again.
I want him to live a long life devoid of hope, calm and peace and abundant in fear, anxiety and intense distress.
RIP Carol, Hannah and Louise 
My sympathies to John and his surviving daughter x
