Thanks for making me overthink this.. Now I can't come up with a reasonable answer, I don't think the line is so clear.. I'm going to say "sometimes". I don't

Thanks for making me overthink this.. Now I can't come up with a reasonable answer, I don't think the line is so clear.. I'm going to say "sometimes". I don't want to go all out (human focused) utilitarian, but not having free rats living with humans is probably a better thing than the alternative, and from a somewhat cynical view, you gave them the chance, and they missed it. We could probably breed relocatable rats in some generations if everyone moved them once and killed those that returned to the human world.
