As for the issue of capital punishment being kicked around in California. Look to the Word of God. Gen 9:5  And surely your blood of your lives will I require; at the hand of every beast will I require it, and at the hand of man; at the hand of every man's brother will I require the life of man.
Gen 9:6  Whoso sheddeth man's blood, by man shall his blood be shed: for in the image of God made he man.
