How was the Aztec culture cruel?

The Aztec culture was marked by practices that can be viewed as cruel, particularly their ritualistic human sacrifices, which were believed to appease their gods and ensure agricultural fertility. These sacrifices often involved capturing enemies in battle, which highlighted the Aztecs' militaristic nature and the importance they placed on warfare. Additionally, the society's hierarchical structure and the harsh treatment of conquered peoples contributed to a culture of fear and subjugation. While their achievements in art, science, and architecture are notable, the brutality of their rituals and conquests reflects a darker aspect of their civilization.
