From the time they were discovered in the 15th century, until they were under control and nearly extinct in the early 20th century, Indians were referred to as "savages". That word was used, by the people who actually had to deal with them, for close to 500 years. To expect anything but gruesome behavior from savages is foolish. The current politically correct view of the noble savage is held exclusively by people more than a century removed from any chance for direct experience.
