Okay, maybe ethical should be replaced with justified. Probably, but that’s not the point.
I believe I touched on this topic before, but the intent was different. So it might seem familiar. Anyway…
I have this isolated non human culture that lives on the polar region of their world. One day, a ship of explorers arrives on their shore. The natives, who do not want to be discovered by the world, don’t know what to do about this. If they leave the explorers alone, they’ll might discover the natives or evidence of the natives, even if they pick up camp and hide. But they don’t want enflame their eventual discovery by just outright slaughtering the entire crew.
So they sneak onto their ship and discover that they are simply explorers with no general ill intent. So they come to the decision to introduce themselves (this might occur as they search the ship) and let the crew live out their lives with or near that natives and help them survive, but forbidding them to leave. The natives will eventually strip the ship down to the last plank for resources, but I haven’t decided how soon that will occur. But they will certainly sabotage it pretty quickly.
However, not all of the crew is thrilled with this arrangement and will try to escape, or signal for aid, or be aggressive, or so on. Shackleton’s crew was about 30 and the natives aren’t sure who to trust and they simply can’t control thirty people for the foreseeable future. So they need to weed out the threats before they can harm their own people.
How might they weed out the threats in a fair manner? Any ideas? I’m looking for inspiration more than answers.
