A Grand Concern For Having Children

Out of all the possible legitimate reasons, as long as someone is free of assumptions and emotionalism, for someone to want to not have children, some get more attention than others: economic difficulty, career development, an unsafe living area, a spouse who does not want a child, mental or physical health conditions, and so on.  Factors like the financial freedom to have a child and be able to give it a comfortable upbringing have become even more overtly recognized even by non-rationalists (not that they can know even this without discovering the intrinsic truths of logical axioms and then making no assumptions).  Increasingly inaccessible economic footing prompts this.

An even more serious, grand factor is beyond the scope of money, earthly comfort, spousal or personal preference, and so on.  While there is a great amount of evidence that Christianity is true, and thus that the Christian afterlife of annihilation in hell or eternal life in New Jerusalem after one's resurrection is true, there is no way for a being with my human limitations to know if there is an afterlife or, if one exists, which of the many logically possible afterlives it is.  There are many afterlives that do not contradict logical axioms which would be dull or horrible, and there is no way to know with absolute certainty beforehand--or even while in the afterlife as long as one's epistemological limitations remain--what the afterlife is like, or if there is one.

For a parent who loves their child, given that they had thought of such logical possibilities, the idea of their offspring suffering in eternal, amoral misery (for eternal torment is unjust, at least for humans) or being crushed by existential terror just at the unknowability of the afterlife while in this life would be of great concern.  The Christian afterlife is not morally terrible either way or of the utmost severity at its worst, no matter how much someone might not subjectively feel otherwise; either a person exists without pain or sadness in a blissful state of eternal life (Revelation 21:1-4), right with or restored to God and free to do all nonsinful things, or he or she will suffer justly and be eradicated from existence on both a mental and bodily level, the body burned to ashes (2 Peter 2:6) as the soul no longer exists to experience torment (Ezekiel 18:4, John 3:16, Matthew 10:28).

There is still a cosmic horror to the annihilationist hell, the real hell of Biblical philosophy, as well as to the everlasting forfeiture of knowledge, joy, peace, and pleasure, and yet this fate is morally good.  The numerous human inhabitants will not exist forever and receive banishment from existence for their unrepentant betrayals of or ideological apathy towards reality.  The real terror comes from it being possible that despite all the evidence for this dual set of afterlives, that evidence is only an illusion, and there is an afterlife objectively worse than oblivion or the Biblical ones.  A rationalistic parent would at least understand the weight of this if they were to think of it, even if they had never previously discovered these truths, and the relevance to bringing a child into the world would be obvious.

Yes, it might be one of the least considered factors, but the logical possibility of different kinds of afterlives is a grand concern for introducing new children to human life.  If the afterlife is something negative that they consciously choose, if it is something they head towards totally thoughtlessly but still because of their own beliefs or actions, or if it is an unavoidable, eternal (and thus non-moral) experience of misery, then it is a far more significant, relevant thing when it comes to having kids than economics or health.  Evangelicals who irrationalistically misunderstand the Biblical hell as one of eternal conscious torment and still rush to have as many kids as they can produce, recalling that the Bible says most humans will walk towards the destruction (annihilation, not perpetual torture) of hell (Matthew 7:13-14), are examples of people who totally disregard the real stakes of their own unbiblical philosophy of justice and the afterlife.
