Human sacrifice is seen with special fascination/disdain/fear by most people, which is understandable to the degree, I believe it has to do with it being a civilian thing with the creepiness of locals participating and cheering on.
It is the same reason why witch burnings and burnings of heretics are so ingrained in the history of Europe/North America regardless of the fact that a very, very few number of people were actually burned(compared to other killings ofc).
It is so apparent that even alleged(to my knowledge unproven) accusations of Carthaginians sacrificing children is still embedded into historiography even after more than 2000 years have passed.
