People like him, on death row, should be used for things that are too dangerous for non-criminals to risk. These scumdogs should be either executed, or given the chance to contribute something - like being used for medical experiments, shot off to other planets in rockets to see if humans can survive, etc. I'd also like to see a renaissance of the Gladiator system, broadcast on Pay-Per-View, with the proceeds going to the victims and/or their families.
