terrible the Spanish slaughtered then like the Germans did the Jews but the reason is not for gold it was that the Spanish saw them practice gay rights and where horrified by it, so they destroyed the Sodom. ever since i learned that i sided with the Spanish. plus a civilization that practices human sacrifice shouldn't survive. lets say they shed blood for a righteous cause. and got some gold to boot!
terribly, they were deceived and treacherously attacked from inside; they even held king hostage. then all gold and treasures were stolen; after that all religious writings were destroyed, just as they did the Incas!
