Since human reproduction is arguably both irrational and immoral, those who seek help before conceiving could be advised it is all right not to have children.
I believe it is morally wrong to cause avoidable suffering to other people. This belief gives rise to two different objections to human reproduction. On the one hand, since all human beings suffer at some point in their lives, every parent who could have declined to procreate is to blame. On the other hand, since potential parents cannot guarantee that the lives of their children will be better than non-existence, they can also be rightfully accused of gambling on other people’s lives, whatever the outcome.
