What is wrong with vengeance? The turd should have thought about the consequences before he repeatedly bashed in the lady's skull.
He was a evil bastard.
And to be honest.... I don't care what some god has to say about it.
Civilized societies reject killing for vengence. We kill because we HAVE to...not because we WANT to. Sadly...the United States stands with countries such as Iran, North Korea and China....while our civilized allies have evolved. The United States is often slower than most to progress.....but we are moving in the right direction.
