Answer:
Yes, in many ways, they were immoral when it came to taking actions towards Native Americans.
Explanation:
After the discovery of the New World, many European countries tried their hands in establishing colonies in unknown lands. Clashing differences between the Natives and Americans led the U.S. government to approve over 1,500 wars, raids, and attacks on Indians. Native Indians ordered to leave their homeland and forced to walks for miles towards that led to known as the trail of tears.
Spain reaches America with conquistador and soldiers in search of gold and riches. Spanish establish colonies and converted many of the Native Indians into Christianity. Catholic Missionaries showed no tolerant attitude toward traditional religious practices. Spanish colonizer killed and conquered old civilizations like Inca, Maya, and Aztec. They introduced the encomienda system.
They should interview other people who fought in that same war ( which would be back up witness for these two different accounts). So whoever has the most back up witnesses must be telling the truth ( also make sure the other people you interview don't know they are back up witness).
Totalitarian is what I think is the answer. But I'm not sure.
