It is an entirely rational position to not want one's resources taken by someone else, especially when the taker does so as a consequence of their voluntary lifestyle choice. There is a coherent case to be made that children do not count as individuals until they can feed and protect themselves - instead acting for all purposes as a 'feature' of their parents or caregivers. In every European nation and most of their former colonies this is state subsidised, i.e. paid for through taxes on men who receive no net benefit.
Provision of abortion treatments provides an option to people who may act on it for their own benefit.
The *only* variable which is not yet determined is if there is a net benefit to a community that filters out the obvious loss makers compared to exploiting said loss makers to crowd out other communities. Historically the answer to that was in favor of the crowders, but with automatic weapons and trait selective abortion that may not be valid any more. Cultures that thought otherwise were fought and bred out of existence and their subjugator's influence is still in place. If the context has shifted through applied science to the point it's maladaptive then the culture will need to shift as well.
So to the OP, who's morals?
The culture that killed and/or bred out their competitors? If you're east or central European this is the Mongols and the Turks. If you're Western European this would be the Vikings. If you're American you yourself are the invader and breeder's spawn back to the 3rd generation easily. If you're Japanese then your ancestors answer for the Ainu. India is an example of outbreeding the invader.
The culture that was never invaded and achieved population control and trait selection through other means? Iceland with its regulated avoidance of inbreeding comes to mind. Arguably the caste system in India which provides a steady supply of exploitable disposables, and preserves the quality as a feature of culture.
The culture that has such historical economic dysfunction that it needs constant influx of native born and foreign workers to survive? (All of Europe and colonies)
If you're asking for where the moral value is determined, I suggest you have not been paying attention to the demands of your surrounding culture.
If you're seeking some outside culture force to make the value judgement for you, there's a name for that.
