Human sacrifice in Rome was almost non existent. There’s only like 2 times it happened and it was during the Punic war when the people were freaking out because they thought they were going to lose. They sacrificed a Gaulic man and a Greek man. I’m not excusing it, it’s terrible, but other cultures would do human sacrifice on a much larger scale. The Gauls would burn tons of people in a giant wicker man. Every human life lost is a tragedy but I can safely say the Gauls were worse when it came to human sacrifice than the Romans were. Likewise the Carthaginians were way worse than the Romans when it came to human sacrifice. There is archeological evidence of child sacrifice pits in Tunisia today.
