The Spaniards were candidates for sainthood, because their mass burnings of heretics were so much more merciful and painless. Glad their God had no interest in reveling in human suffering and blood since burning to death was so much less bloody.
The Spaniards never sacrificed 80,000 people on top of a pyramid in one weekend like the Aztecs did on the Templo Mayor pyramid in 1487. Perhaps that one act so horrified God he sent the Conquistadors to properly chastise the demonic Aztecs.
