I've never read nor heard your interpretation of that passage in The Gospels.  That's a new one on me.  And altho' I think it's a perfectly rational one, I think you're interpretation is very wrong.  ////  I can tell that we're not communicating at all.  What I will say is this:  you are certainly entitled to your opinion, but support, among US citizens, decreases every year.  It's now at about 50/50. And, God willing, we won't have it much longer.  Even Pope Francis calls it very wrong:  "The death penalty is inadmissible to matter how serious the crime committed.  It is an offence against the inviolability of life and the dignity of the human person, which contradicts God's plan for man and society, and His merciful justice, and impedes the penalty from fulfilling any just objective. It [the death penalty] does not render justice to the victims, but rather fosters vengeance."  I'll hang with Pope Francis and The RCC on this.
