Agreed about #4 (the guest in your lair).
Also, depending on interpretation, I think #6 (“Do not take that which does not belong to you unless it is a burden to the other person and he cries out to be relieved”) could be a problem. I may be putting too much into it, but the wording there is odd. What do they mean by “cries out to be relieved”? Because he’s complaining about something related to his possession? (But not necessarily asking for it to be taken away?) Maybe he’s bitching about his wife or his car. Does that mean that they can be taken away? If the wording were “unless he asks for you to take it from him” that would be much better. But perhaps I’m reading more into it than I should.
The other one that troubles me is #11 (“When walking in open territory, bother no one. If someone bothers you, ask him to stop. If he does not stop, destroy him”). What do they mean by “bother” and what do they mean by “destroy”? If someone “bothers” you by sitting next to you on a bus and eating marshmallows, even after you (unreasonably) ask them to move to another seat, is it okay to “destroy” them? That sounds incredibly selfish. In the real world (and especially in the military), we all have to tolerate being “bothered” and we can’t go around “destroying” people who won’t stop “bothering” us.
