They may have,but the Aztecs were here and they were as bad or worse. Aztec priests would drag some poor fool up the steps of their pyramid lay him out on an alter hold him down while another one would take a razer sharp obsidian (black glass like stone) knife and cut his beating heart out. Afterwords the rest of the crowd there would EAT what was left of him. Cortez wrote of this in his diary when he conquered Latin America.
Yes. This point is routinely overlooked. The Mayans and Aztecs didn't have sheep or goats or any kind of cattle. Their pyramids provided the municipal meat supply.
