How were the The Aztecs and Incas were treated by Cortes and Pizarro.

It was a massacre peopel were raped houses burned 1000 years of progress wiped out by the spanish. Imagine if they had more time to progress they would have been just as advanced in 100 years imagine if an alien race came to earth and killed us becuase they were more advanced that is what the massacre of the natives was like.
