if you're just looking for a sense of purpose or belonging then you need to live for yourself, don't put that burden on a child for no reason other than that, have a child because you yourself want to cherish that soul and share experiences with them.
i also agree with the world being incredibly cruel so therefore you shouldn't bring one into the world because of that, but that's moreso just an opinion so if you're able to fully support them (not just monetarily) and want one for the reasons i stated earlier then it's good to have one because at the end of the day it is your life and you should do what YOU believe is right and what YOU want to live for.
but if you do genuinely want one pls understand the responsibility that comes with having a child, it's super intense and scary (not that you shouldn't have one because of this, just that it's extremely hard to raise one).
i believe in you no matter what you do <3
