Actually, Norway's criminal deterrence system is quite interesting. Growing up in the United States or Europe, we're used to deterring criminals through punishment.
In Norway, however, they deter crime through rehabilitation. Ironically, they have a significantly lower prisoner-citizen ratio.

I actually like the idea, it seems a bit utopian - but it has worked for them.

Really I find this odd. I do not like the idea one bit. Why live like a king when you killed someone? Does not make sense at all. If you kill you do not deserve to be treated like royalty.

He is by no means living like a king. He has no freedom, he's stuck in that small room, and he can't go anywhere for the next 21 years of his life.
If anything, he's living in a very small but isolated room. It's not like they are rewarding him but it isn't like they are punishing him either.

No I read that in Norway the can and will give him a repeat sentence once his current sentence is over.

Yeah I've read that somewhere too.

EquinoxRhyme is correct. If he is still deemed a threat to society they can and will keep him there longer.
