Columbus wasn’t much a a villain but the Spanish he brought in and their culture at the time were villains. Remember that the Spanish were pretty much reviled by the rest of the world because of their approach to anyone not Spanish Catholic.
On the other hand, the Spanish didn’t do anything to any group of Indians than the individual tribes did to each other. The idea that Indian tribes all lived in harmony with each other is as big a load of crap as the idea that anywhere an Indian took a dump is sacred ground.
Migration and conquest is an enduring part of human history and there is no turning back. Tribal associations always lead to intertribal warfare and the eventual collapse of whatever civilization they have built. They need to move on.
