I'm not convinced the death penalty is worthwhile except to feed someone's wrath.
What if, (and hear me out,) we did for corrections the sort of thing that countries with low recidivism do? Like, not use for-profit prisons with incentive to turn out re-offenders, and not use prisons that turn out hardened criminals that aren't equipped to function in the world without resorting to crime, and actually take the 'corrections' or 'rehabilitation' parts of their nomenclature seriously?
If all we do with our prisons is punish and humiliate (and squeeze slave labor out of) convicts, we're just creating future crime and all that's left at that point is killing convicts at industrial pace unless you can figure out that crime is more driven by poverty than anything else, and the USA just doesn't want to figure that out because it just doesn't want to solve poverty or crime, it wants to make money creating and punishing both.
