I don't know where they let dangerously deranged people wander loose, but if your movements are utterly restricted, it doesn't matter how clinical or otherwise gilded the cage is, it's a cage.
You can CLAIM someone is 'rehabilitated'. I'm sure you'd trust your own kids to be left with a 'rehabilitated' child rapist/killer as a teacher at a boarding school, for instance.
And a minor correction: In the U.S., they're warehoused, or just stuck in a prison population.
Even the people who haven't murdered other people are just chucked out on the streets and left to fend for themselves.
Strictly speaking, I'd rather die than go to prison.
To call death 'inhumane' is to call being born 'inhumane'.
Everyone is born with a death sentence.
Not every broken brain can be 'fixed'.
In fact, nobody can PROVE that someone is 'rehabilitated' to anyone else's satisfaction. WHEN a convicted murderer, rapist, etc. is released, there is something called 'recidivism'. That's when someone who commits a crime, is released, and commits ANOTHER crime, and ends up back in prison.
Exactly what rate of recidivism is acceptable to you, among murderers and rapists?
Even killers in prison populations kill again. And then they go to 'solitary', which is literally never being among other human beings again. But kept alive. Oh, yes. 'Alive'. In a box.http://www.prodeathpenalty.com/repeat_murder.htm
