I'm convinced that the catholic spanish were given mexico (literally delivered into their hands by God) precisely because of the meso-americans worship of huitzilopochtli and tlaloc in really perverse ways like the sacrifice of thousands of people and the resulting wars needed to create a constant flow of sacrificial victims. It turns out that while the spaniards were brutal, proud, arrogant, greedy af and at times tyrannical, they were always far better than the Aztecs.
