If the crimes are heinous or numerous enough and the evidence strong enough to warrant incarceration for life without the possibility of parole (or an equivalent sentence like 100+ years), why should taxpayers be forced to pay for a criminal for the rest of the criminal's life? Why not simply execute them? If they can't be let near society ever again, why was the money for food, water, electricity, clothing, and medical care for someone who had to be permanently removed from society? Rope can be as cheap as a few bucks a foot and still hold all the needed weight. Steel cable can be had for a buck per foot. An axe costs fifty bucks and is reusable. How much does it cost to get a can of nitrogen or CO2 and hook a mask up to it? How much does potassium cyanide cost? Instead, we punish society through taxation for following the law and reward those criminals with free room, board, laundry, medical care, and other comforts for the rest of their lives.
