I don't begrudge anyone not wanting kids. It's not for everyone.
That said, my first thought when I saw the post title was "I don't regret having kids".
I suppose the caveat is that my twins are only 2 and a half, I may well regret having kids when they start getting pregnant, selling drugs, marrying chat bots, that sort of thing.
Edit: I just scrolled through some of the other comments and noticed that the majority of them say that they don't regret not having kids. The fediverse is pretty homogenous I guess.
