Amazing story! Thanks for posting.
It reminds me of the scene in It's a Wonderful Life, in which George sees his brother Harry's tombstone, and the angel says "Harry drowned when he was 6 because you weren't there to save him," and when George says "that's not true, Harry was a war hero who saved an entire battleship," the angel replied "all of those sailors died because Harry wasn't there to save him."
One life certainly does affect every other life around it, which is why we can't simply make abortion "safe, legal and rare" but nonexistent.
