I did not say I personally do not consider it wrong, but I live in a society where there is no need to control numbers, nor not enough money/resources/etc to support those children. If we do not want any we know what we can do against it. In view of what has been said below your post, it shows that it is wrong subjectively, but not objectively. In India, they still kill babies (mostly girls). People from the same culture do it the UK for the very same reasons. Why?
Look around you. Do you see objective good? I for one do not. I see subjective good and some of it largely overlaps with my conception, but it does not mean that it is objective.
Socrates acknowledged that one can only desire the good, yes, if one knows oneself and pursues happness (which fulfils one's soul). If one does not know oneself one may do the bad which stems from ignorance. So essentially, he says that every man has the potential to be good and do good, but that he may do the bad if he is ignorant that he is doing it or pursues what he thinks fulfils him. He also professed he only knew that he knew nothing noble and good. Plato defined the quest for wisdom and the mind as a process of learning to refind the Ideas in one's mind that are constant and come from a divine being. As man is living in a non-constant world, these Ideas are obscured and man may never find them back again.
The question is, if your tribe is starving and finding water is difficult, whether it is beneficial to have yet another mouth to feed. The whole tribe may die if you let the baby live. Is it wrong to kill the baby? Of course now it is wrong (subjectively) because we can live if we let the baby live, but is it objectively always wrong to kill the baby? Is it wrong to kill it or let it die if there is not enough food to give it? I suppose that depends on your end.
And that is the pot calling the kettle black because they killed their own. Oh, no, wait they thought it was better to just abandon them to die from hypothermia or something.
I have grasped morality so far that I see that it is relative. I think that is a little further than you have come.
And we are seriously off-topic here. Maybe the moderator finds this amusing?



Caught me, I'm in "resolution" mode now. Also I've thought about this a lot (really) so it'd be weird to not say anything after reading this thread.



. Hitler bought the whole thing as well
and issued a certificate of descent or something. That is frankly laughable.
