To paraphrase: A people is judged by how it treats the least among them.

The idea of sensory deprivation of the depraved and convicted among us on the surface is an appealing (no pun intended) one but unworthy of us, imo. We might as well give the person a lobotomy or drugs that make him actually crazy or use him for body parts or medical experiments.

And what if the person suffers ten years of extreme deprivation with its attendant consequence - and then we find irrefutable evidence that the person was innocent of the crime? How do you make that up to him? It is not only capital punishment that has irrevocable consequences.
