“I don't see any reason why that would be untrue. I mean it would be shocking to actually see that happen and Cortes when Montezuma invited him to the top of one of the two great pyramids in Tenochtitlan he remarks the priests were adorned from head to foot in black clay or body paint and and the interior was was black with with spilled blood and it stank.”

“stank of bomb the beast so i don't see any reason why”

“They wouldn't be genuinely mortified by that.”
