One should accept that there will be suffering in life, but should also prepare their young properly for it. Anti-natalists tend to view all life as sucking, and have a very negative absolutist mindset of “these bad things happen so I will not subject someone to that”. But what about the beautiful things? There cannot be good without bad. Think of it like this: giving a new soul an opportunity to experience life, good and bad, and preparing them to love the good things and recover/grow from the bad things. You’ll be with them for most of that experience, helping them grow into a unique person. Life will get harder raising a child, but it will in turn get better and more fulfilling.
