Now the case could be made that a parasite usually lives off a host that belongs to another species, which is clearly not the case with embryos, but to claim that it “benefits the mother” is just weak.

Benefit in biology is survival of genes as much as individual life. It absolutely is a benefit in evolution to propagate genes.
It isn’t a weak argument at all. The baby is a biological benefit. I agree that it’s a cold way to look at it, but that is the scientific truth.[/quote]
So that makes pregnancies very beneficial for the genes that get carried on, but not necessarily for the mother.
Since evolution does not care one way or the other I doubt that anything can be beneficial to it, but if you want to go down that road, there are a plethora of situations where reproductive success could actually increase with an abortion or infanticide, which is why at least the latter happen quite frequently in the animal kingdom.
Also, why would anyone care what evolution wants? That is somewhere in the realm of not building planes because gravity does not “want” us to fly.

Then scientifically define benefit as it relates to biology.
So, this isn’t about science then? We should decide based on ethical reasons?
Cause I like that argument even better.[/quote]
First of all you cannot “scientifically define” anything as “beneficial”.
Second, if you could, it would still be “unscientific” to make an abstraction like evolution the arbiter of what is beneficial.
Third, said “evolution” kills more innocent life than the cholera, which is kind of logical given that the cholera is part of and not greater than evolution.
Fourth, you started the ethical discussion by drawing rather crude biologisms into it, which of course immediately begs the question whether we as a species have a good track record of doing what nature commands, ironically that does not seem to be part of our nature.
