Would you want their organs?
That question surprises me.
I wouldn’t want to be in a position to need anyones’ organs, but if I were, I wouldn’t expect whatever towering evil infected their souls would apply to their kidneys.
My point is that they should be locked up for life since they won’t be executed, and rather than finance that utter waste of every input to that equation, perhaps their time on earth (whose EBT card they cashed in and then some) can be morphed or moved into someone else who might live a modestly productive life.
