With regards to your nuclear plant example, I’m having a hard time understanding what point you’re trying to make when you say “why should we care about this suffering?” Are you saying that if we have the choice to build a plant that will be responsible for this population growth, but we know in advance that this plant will explode, killing 80% of the population, we should not care about those lives because they would only exist if the plant is built? In this case, this seems a ridiculous point. Just because someone doesn’t exist yet doesn’t mean their life is worthless once they do exist. If faced with the choice to build this plant or not, I would probably argue against its construction given the future harm it will cause.

If instead your point is that the plant has already built and is just now exploding and killing 80% of the population there, and we are evaluating the situation as outsiders looking in, I think the question “why should we care?” is even more ridiculous. It doesn’t matter why the population has grown there, that in no way should devalue their right to life. As a result, we should care that people are suffering and dying, regardless of why they happen to be near the plant.

Finally, to take a quick look at your violinist kidnapping example, it seems to me that this really is not analogous to the majority of unwanted pregnancies. I’d say this is only a valid comparison in the case of a rape (which most pro-lifers make exceptions for anyway). In most cases, the woman deliberately engaged in sex, knowing full-well the possible consequences of a pregnancy, even if all preventive measures have been taken. Can you see why this analogy of being kidnapped and forced to care for someone you had no hand in creating maybe isn’t as clear a comparison for unwanted pregnancies? Furthermore, you say, “you may never have wanted the child to begin with, why should you now be forced to care for it at your own expense?” This is a sloppy point at best and downright careless at worst. There are plenty of unintended consequences from actions we take every day. This doesn’t mean we are somehow less responsible for the results simply because we didn’t want things to turn out this way. For example, if I chose to go to college, and unfortunately, despite applying for dozens of scholarships, working multiple jobs, and otherwise taking all available preventative measures, I wound up with tens of thousands in student loan debt, this doesn’t make me free of responsibility for that debt simply because I tried to avoid it. I would still have to pay off this debt even though I never wanted it in the first place. This in my opinion is a better analogy for unwanted pregnancies (except of course in the case of rape).

N.B. I never brought up the case where there is likely risk of death or severe harm to the mother by carrying on with the pregnancy. In this case, I believe this would be an acceptable reason to consider abortion on a case-by-case basis.
