Some Rabbis are clearly corrupted by our decadent culture. How come we have Rabbis like Eliezer Waldenberg “permitting” aborting Down Syndrome babies, “extenuating circumstances”, and the like, apart from danger to the mother? The Gemara is very clear in many places that abortion is part-murder.
But as attitudes worsen around us, Jews learn from the Non-Jew. And pretend the Torah itself permits murder.
I highly recommend Rabbi Brand’s tiny book on abortion here (Hebrew).
