I want to know the answer to the following question:
What act was repulsive to Romans?
All the background I'm provided with is that "After the Roman defeat at Cannae two Gauls and two Greeks were buried under the Forum Boarium, in a stone chamber "which had on a previous occasion [228 BC] also been polluted by human victims, a practice most repulsive to Roman feelings".". Is that enough to answer the question?
Answer: no
