Less indecent if it’s remnant from the days of a famine.

A mistake a lot of people make in analyzing the text is in assuming the official story about its origin, contents, and authorship is correct outside supernatural stuff.

But there’s actually a compelling case Noah was originally a story about escaping a famine, so there may well have been a period when eating the flesh of one’s children was a part of the ancestral history of the people transmitting the stories.

The Geeks have similar stories.

It may well be that Deuteronomy 28:48-57 isn’t a warning about a certain future event, but a warning from similar things having happened many times before.

Eating your family because an army whose language you don’t even know is sieging your city and you are all starving is probably just a fairly common part of many generations of history around the world during those times.

There’s much worse things in the Bible than likely representative history.

Or pretty much all of Song of Solomon.

Example (Song of Solomon 7:6‭-‬9):

How beautiful you are and how pleasing, my love, with your delights! Your stature is like that of the palm, and your breasts like clusters of fruit. I said, “I will climb the palm tree; I will take hold of its fruit.” May your breasts be like clusters of grapes on the vine, the fragrance of your breath like apples, and your mouth like the best wine. May the wine go straight to my beloved, flowing gently over lips and teeth.
