I am familiar with the argument, and I realize you aren’t necessarily supporting it. I support the death penalty for real murder, forcible kidnapping, and forcible rape (which would include child rape in all cases), because it’s biblical, and I trust God in re: his law.
I tend to agree with you, actually, though I am uneasy in my agreement.
I would hate to think of the death penalty actually causing someone to be murdered.
But I do agree with you in principle.
