Well I think that that creep from Norway needs to be locked up in jail for ever.
While I do not wish that another member of the prison population should shash in his skull with a broom stcik (like J Dahmer) I think an effort should be made to make sure he does not enjoy his time in the prison. I think that he should be required to share a cell with a group of the local drunk drivers, wife beaters and whatever other dregs of society which happen to be in jail.
I think that his cell mates should be given orders not to physically harm him, but to feel free to do things which will irk and annoy him. They should also be given a deal that anyone who saves him from being attacked by another prisoner or stops him killing himself will get a big reward. Thus the cell mates will act as his bodyguards to keep him alive so the punishment can be continued for a very long time.
I think he should be given some form of work which is horrible and never ending, the work should be designed to be very sisyphean in nature. I think that the brightest minds in norway and north europe should address this problem to design a sisyphean task which will torment him but not physically harm him. One suggestion I have is to get 4 tons of 5 mm stones in a pile. Then make him move the pile using a plastic beach spade and bucket to the otherside of the room. Then make him move it back again. Or make him paint the floor of his cell with a toenail brush, each week it would have a different colour.
