Wow, truly awesome post Kris! It is a master class on the reasons to and not wanting kids. Of Witch an outcome of love and purpose being the best and healthiest. You hit all the pitfalls and pluses and should leave the readers with no doubt where they land on the subject of having kids. You hit on the timeless debates of the subject and even the new issue of gender and other new developments in parenting.
Personally, I would fear passing on illness, mental or physical and raising a little psychopath that murders a bunch of people.
