One of the Ten Commandants is, Thou shall not kill. Does this apply to animals as well?
The Decalogue is a very poor piece of drafting.
Rules 1- 4 are about maintaining the authority of the religious establishment.
Rule 5 is apparently a social services provision. If so, not a bad idea.
Rule 6 says "Thou shalt not kill," or "Thou shalt not murder". As 9/10 Penguin has already pointed out, this means "Prohibited killing is prohibited". It says nothing about defenses of self-defense, insanity, necessity, childhood or accident, nor of the role of negligence, nor the specifics of intention, nor the status of tribesmen as against foreigners, and so on.
Rule 7 says, Thou shalt not commit adultery. Unless of course you're the King. And anyway you can have as many 'wives' as you want, though that arrangement isn't reciprocal.
Rule 8 says, Thou shalt not steal. This has the same problem as Rule 6: "Prohibited taking is prohibited". It too should instead state a principal eg: "Do not take the property of another tribesman or -woman or the fruits or benefit of their labor, or deprive them of any entitlement, without their free consent; if you do, you must pay them full compensation &c and a fine &c."
Rule 9 says, Thou shalt not bear false witness against thy neighbor. That seems unduly narrow. "Thou shalt not make untrue statements, or statements calculated to mislead, about your fellow-tribesmen and women: if you do &c."
Rule 10 says "Do not covet the property of your fellow tribesman." Since we should already have a rule against theft, perhaps here should be a rule against conspiracy to commit an unlawful act.
Rule 11 says "Thou shalt not park so as to obstruct thy fellow tribesman's driveway." This might be included instead in some more general injunction to behave civilly and considerately at all times.
Rule 12 should specify that for purposes of the rules, slaves of fellow-tribesmen have the same rights and obligations as fellow-tribesmen.
And we need some rules about assault, battery, blackmail, fraud, the right to privacy &c.
And so on. An opportunity lost.
