You may want to read the entire history -- this was a effectively dispute over what the Crown owed Columbus... and he demonstrated via the courts in Spain the allegations of brutality were not proven. After this he was allowed to go on his fourth voyage - as well as having his wealth restored after a
court case in his favor.
The actual complaints about Columbus from others on his voyages were more around his straight & narrow religious views -- with complaints from others that Columbus expected them to act like monks (at least in regards to "relations" with natives). However Columbus fully supported enslavement of the native population -- and with this came brutality.
There is both good and bad in regards to Columbus' voyages. The bad is that his voyages led to generations of brutal enslavement and poor treatment of native Americans by Spaniards. The brutality of other Spanish explorers goes far beyond anything Columbus did -- but he opened the door for it.
The Dominican Republic has a more nuanced view of the Columbus. They view that he established a basis of their "excellent culture" and Spanish heritage while at the same time putting in place generations of "poor government" -- at the same time they do not gloss over the bad related to Columbus. Yet they don't understand why people in the United States are attempting to erase Columbus from history -- after all the Estados Unidos was not impacted directly by Columbus. Better off to teach history -- including all the good and bad parts.
The Dominican Republic has a huge museum dedicated to Columbus (the "
Columbus Lighthouse" aka "Faro a Colon"). There are statues and tributes to Columbus across the country. I have visited Faro a Colon while working in the Dominican Republic.
