@coldjoint,
I am not sure if you understand the Golden Rule. The point of the Golden Rule is that it governs your behavior based on how you want to be treated yourself. The way that anyone else acts is irrelevant to the Golden Rule. Jesus was pretty clear about this; you are supposed to do good to those who mistreat you.
But that isn't the point.
You are claiming an absolute moral principle; the "sanctity of life". If you believe in the Sanctity of Life that means that you wouldn't accept the taking of a life in any circumstances, not capital punishment, not "stand your ground", not let people die from lack of food or medicine.
You don't seem to even follow your own absolute moral principle.
