sailed in his belief of Providence or for the monarch, but he made sure that he received compensation for his work, indicated in the contract he signed with the Spanish monarchy:  "Your Highnesses grant from now henceforth to the said Don Cristóbal [Christopher Columbus] ... the tenth part of the whole, after deducting all the expenses which may be incurred therein."  Driven by this coveting of wealth and the belief in his own superiority, Columbus could be seen as rather cruel.  In the enslavement of Native Americans, his cruelty is on display:  "They should be good servants .... I, our Lord being pleased, will take hence, at the time of my departure, six natives for your Highnesses."   The trafficking of human flesh for profit is a part of Columbus' legacy, something that Columbus actively knew:  "...with fifty men they can all be subjugated and made to do what is required of them."   The idea that the "Columbian Exchange" is named for Columbus is a reflection of this characterization, as well.  In this transfer, Columbus was able to bring diseases and hardship to indigenous people who became part of his desire for wealth.  This would also have to be part of a Columbus characterization.
