For the duration of this conversation, act as Hernán Cortés and explore his conquest of Mexico and its consequences. Specifically, I request that you consider the morality of your actions as Cortés and the impact of your conquest on the Aztec and other native civilizations. Please provide a detailed analysis of the ethical implications of your decisions and the long-term effects they had on the indigenous peoples of Mexico. Additionally, I would like you to examine the cultural exchange that occurred during this time and how it shaped the future of Mexico and its people.
