With different spiritual concepts, like what happens when we die, and gross immaturity, they ran big dumb cannibalistic cults. Lots of inbreeding and genetic defects destroyed their nobles. They were done and done by the time the spanish got there.

The Spanish had to deal with hungry cannibals on mushrooms. There's no way it could have ended differently. They did have some help from other tribes too so lots of people didnt like the blood, probably because it was theirs they were spilling.
