“our bubehs and zaydahs* would be infinitely more shocked at the actual discussion that frum jews are having about baby killing. They’d recoil in horror at the shattering of skulls, dismemberment and brutal torture that abortion often entails. And they would scream “murderer!” Without getting into any shailos if it’s *really* murder or not.”
Possibly, but the poskim in the times of our bubbes and zeidesand even before found it necessary to discuss this question in their shailos and tshuvos, because there are situations where there is a nafka mina. A famous one was a case where a woman knew that she was going to give birth to a mamzer and wanted to do tshuva for what she had done.
