Yes it's never going to be perfect when trying to overlay a closed system of logic on the open system that is the universe, but we've shown ourselves pretty capable at getting to good enough.
In this case it is a question of what is "good enough"? Meaning, what are we trying to accomplish?
I'd always been mostly ambivalent toward abortion but thinking about it more recently, it does seem quite the tragic and brutal practice.
I'm inclined to believe you that no one does it for fun, at least in retrospect. I think there is a problem of too much of a glib attitude about it from the SJW/Tumblr types which hides a lot of the torment an abortive mother is likely to feel after going through with the procedure.
I'll repeat: What is it about our society that compels women to do this?
