Well, I Suppose That's One Way to Look At It

Here's a passage from the article I'm currently reading on political thought during the Restoration Monarchy in Britain from the 1660s to the 1680s:

"The clinching argument [for the Tories] that sovereign authority must be God-given was that rulers had the right of capital punishment. Since the Commandment enjoins, 'Thou shalt not kill', the right to take life could not have been transferred by the consent of the people, for it was not a right that the people had to give."

That's... an interesting argument, seventeenth-century Tories. Observing that your religion says killing is wrong, and that your kings possess the power of capital punishment, your conclusion is not that this royal power conflicts with the relevant Commandment and is therefore wrong, but that this is evidence that the kings have a kind of quasi-divine status that exempts them from the Commandment. Interesting.
