Would doing the same thing to a criminal as they did to their victim be vengeance or justice? (Example: sodomizing, torturing, and killing a murdering rapist.)
No. We're better than doing the same thing back, whatever the rationale is. Or at least I like to think we are.
Two wrongs doesn't make a right.
It would be ridiculous, and should get us booted from every international anything.
I'd be down with stoning him, if I could just quit being reminded of John 8:1-11. +++
I'm with you for once. Life in prison is far worse than any other punishment.
