I think that you have a well-reasoned and valid view. It's not that I regret my birth, but that I didn't consent to being a living, conscious thing -- the consent portion of which you can reasonably view as an impossibility.

Suffering is a necessity of living, and therefore bringing a person into the world means they will suffer. You're right that I generally take a utilitarian view of things, upon reflection. Though, taking it to its most extreme conclusion, I could never be asked to choose between saving 5 million people if it meant killing 4,999,999. Such thought experiments leave me confounded.

Maybe it's the case we're faced with infinite impossible choices because the universe doesn't care and tends towards entropy. There is likely no perfect answer. All I can do as a person is try to beget as little pain into world as possible, but I recognize that my view isn't without flaw or applicable to everyone everywhere all the time.

This is also why I don't simply despise people who have children, like my own parents.

I appreciate you taking the time to explore this with me! Genuinely much food for thought.
