Why was Christopher Columbus considered a ruthless leader?

Christopher Columbus is often regarded as a ruthless leader due to his brutal treatment of indigenous populations in the Caribbean. His expeditions led to the enslavement, violence, and significant suffering of Native Americans, as he sought to exploit their resources for profit. Additionally, his governance in the territories he claimed was marked by tyranny, including harsh punishments and a lack of regard for human rights, contributing to a legacy of colonial oppression. These actions have led to a reevaluation of his historical significance, painting him as a controversial figure rather than a straightforward hero of exploration.
