The Hippocratic oath doesn't cover this at all and actually explicitly forbids abortion and euthanasia. It's really quite antiquated which is why I wrote an oath for myself that I hold to.

There's a lot of debate about the specific meanings of the text, but there are many Christian physicians that will latch onto those passages as an excuse to apply their own beliefs to patient care. https://en.wikipedia.org/wiki/Hippocratic_Oath

The oath is a promise, not a law. People break promises all the time.

not mistaken, but certain roles like pharmacists, cashiers, nurses, dentists and lab techs dont take that oath. Many doctors now take alternate oaths too, not the original oath.
