There is no debate over whether the Aztecs engaged in mass human sacrifice. The main disagreement amongst academics is over the scale. The Aztecs themselves claimed sacrifices of over 40,000 people, but they obviously had good reason to lie (to scare enemies). Spanish and pre-columbian Aztec sources agree that human sacrifice was widespread amongst the Aztecs.

You’re quite right; I should have been more explicit. Edited.
