Really, these people are still barbarian peasants both morally and societally.

Even in the Bible, when the Israelites were in captivity, they begged Pharaoh to let them go into the desert (for three days no less) to do sacrifices. Moses and Aaron said that if they didn't that "God would put them to the sword". Which was a straight up lie.

Animal sacrifices (esp. human) are barbaric to most people. There was a video on here recently of the five red heifers that Israel obtained from Texas, and everyone was all smiles choosing which cows they were going to kill. They even have a whole organization for it, Boneh Israel.
