Given the heritable and functional consequences, perhaps the Biblical penalty for adultery, bestiality, homosexuality, or pedophilia is somewhat more understandable given that these families had to breed sufficient young men to be capable of holding off the likes of the Babylonians, Egyptians, Assyrians, and Hittites. Israel was known for its fecundity until the time of the Roman Empire.
Didn’t even realize I had one until you mentioned this.
