I think I have a fairly cynical view that reproduction is primarily a selfish act based solely on our biological drive to continue our species. I've pondered for a long time, and I fail to see a more logical conclusion than that.

Life is tough and there are no guarantees. Rolling the dice by having a kid seems like a messed up thing to do imo.

That said, I would adopt a child or children. That's a better way to ensure you are putting kindness and hope into the world where it's needed, rather than creating another vessel for pain from whole cloth.
