There is no law that provides a satisfactory outcome to that. I agree. In the past, someone said that if you want to murder someone, do it with a car. The resulting sentences will always be light.
Jeremiah 39:6 ~ King of Babylon slays Zedekiah's children in front of him and then he is blinded. So the last thing he saw was murder ~ the folks who put the Bible together definitely thought of it as a horrible thing to happen, and back in the day those old boys were pretty rough. We give a drunk driver a couple of years, tops, for murdering a family.
There continues to be a place for drawing and quartering in our world.
