I'd rather they just lock him away in a room in which the faces of the people killed by the plot that he was involved with are constantly being projected onto the walls. Also provide an audio track with their voices and their eulegies being read by friends and families. Make sure that it is something that he can't avoid.

Let him spend the rest of his (hopefully long) life learning and thinking about the pain and suffering that he has inflicted on so many innocent people. I see no reason that this should be considered crual and unusual since he has continued to show no remorse.
