Divine Law
"Whoever sheds the blood of man, by man shall his blood be shed; for God made man in his own image" (Genesis 9:6).
"Let every person be subject to the governing authorities. For there is no authority except from God, and those that exist have been instituted by God. Therefore he who resists the authorities resists what God has appointed, and those who resist will incur judgment. For rulers are not a terror to good conduct, but to bad. Would you have no fear of him who is in authority? Then do what is good, and you will receive his approval, for he is God’s servant for your good. But if you do wrong, be afraid, for he does not bear the sword in vain; he is the servant of God to execute his wrath on the wrongdoer" (Romans 13:1-4).
This is Divine law; Old Testament and New Testament, unchanged. It is not merely an invention of human society that can be jettisoned because we are too squeamish to believe God. Just in case anyone tries to say otherwise...
