Yanomamo

Changnon's actions were worse than Good's. What Ken Good did was immoral but from what we know he wasn't too violent of a person. Changnon provided the people with tools such as machetes and basically got them to use them against each other. Not that they weren't already violent people, but this sure didn't help. Instead, it caused more lives to be lost. At least Good's original purpose in being there was for research.
