What someone would do in a situation does not change the facts of that situation. Whether one would choose to save the toddler or the embryos does not change the fact that they are all human beings. Imagine a similar situation in which a man is in a classroom with his own daughter and 25 other children. If the room is on fire, the father would most likely save his own daughter before the other children. But this does not mean the 25 other children are not human. What it tells us is something about the father’s psychology—that he is more attached to his daughter than the other children. It is totally unrelated to the humanity of the other 25 kids. Similarly, if someone were to save the toddler before the embryos, this would tell us something about the person doing the rescuing. But it would have no bearing on the objective humanity of the human embryos left behind. Thus, while this question is interesting psychologically, it is irrelevant to the humanity of preborn humans. Regardless of what any one person would do in any situation, the preborn are human beings we should not purposefully kill.
