That’s all well and ghoulish, but the title doesn’t make any sense, as they didn’t abort the second child, how can it be “his” abortion?

Yea more like his “murder in the uterus”

...but the title doesn’t make any sense, as they didn’t abort the second child, how can it be “his” abortion?

Because the father tells himself that the mother of their child aborted the first child for the benefit of the second child. "You're alive because we killed your brother. We did it for you."

No, they did it for themselves and it's sick to pin that on the second child.
