One major difference is our genetic wiring. You’ll find that many many people with kids you meet say “I was pretty sure I didn’t want kids, but once you have them you wonder why you ever thought you wouldn’t want them.”

So the answer is yeah, if you did have kids you would probably not regret it. It’s just one of like the only 3 things we evolved to do as human beings, your body gives you really strong incentives to take care of your kids.

But if you never have kids you can also not regret it and both can be true.

“Probably” is doing some heavy lifting there. My mother regretted having me, and was never shy about it. She’s the one that decided against the abortion, but somehow I was the one that ruined her life by showing up. My entire life, I’ve felt like I should kill myself and finally make my mother happy.
