Very bad idea.
A slippery slope that will take us who knows where.
I have no objection to the death penalty, but the purpose is for society to have the wrong doer pay with their life, not be a source of body parts.
Like many things, something that starts out one way soon evolves into something entirely different.
You are absolutely right. I withdraw the suggestion.
Larry Niven wrote of that. Demand for organs to the point that even speeding tickets had a death penalty.
Still, it has a nice poetic ring to it...
