It is far preferable to sacrifice primates, bunnies and puppies to test life-saving drugs…
…than to kill human children and/or create human-mice hybrids!
If a dying man can donate an organ, is that a sin? If a dying fetus can donate a few cells that end up saving millions of souls, is that a sin, too?
or we can go back to the good old days in Ireland where the church didn’t allow ectopic or breech or detached placenta or blood incompatibility, or sepsis, or a dozen other maternal emergencies, to be medically treated and the women would die a horrible, painful death over days or weeks. That was back when the average age at death in western civilization was 35.
And we can’t use puppies and primates any more because peta. Which pretty much leaves rodents.
