As I understand it, Columbus' men forced natives to mine gold and punished those who refused. Other atrocities also. Columbus was detained briefly for these crimes. He was not a saint, but he did open up the new world. He was a great explorer and adventurer, but maybe not a great guy. You have to put it in the context of history. Spanish, Portuguese, Dutch, and English, all committed similar crimes in their efforts to "explore." Sorry, lots of history sucks like that. You can't just delete it all. It's who we are.
