There is nothing, NOTHING, beyond the pale of some people and some cultures. The Aztecs and Maya would cut the heart out of living people to appease their gods. Many Asian cultures still practice infanticide by exposure. Most often leaving unwanted girls open to the elements to die from starvation or exposure.
The Romans had no issue with abortion & infanticide. They where also employed decimation in order to discipline their troops. Crassus used it in 71 BC During the Third Servile War while fighting Spartacus and his renegade slave army. Julius Caesar threatened his 9th Legion with it while fighting a civil war with Pompey the Great and the Republicans, though he never employed it.
OK, but the claim was that it's well known that the Chinese eat fetus soup, which is ridiculous.
