C. I can see where you are drawing parallels but I don't think that this episode can be a valid example for our discussion here. The aliens were not humans to begin with.
So, your are rather anthropocentric, aren't you? Anyways, do you think the aforementioned robot would intervene when accompanying the birth control squad? (After all, the robot doesn't know the big picture you explained (=the broader context), and burning the innocent eggs for the sapient aliens would be classified as rather a horrible act, won't you think? Do you think the bipedal beings absolutely legally doing birth control that way deserve to be called humans?
