saw this yesterday on national geographic while avoiding the world and all I could think was I was trying to get away from the news

In 1994 a small child in western Uganda was attacked and partially eaten by a wild chimpanzee. This was the first casualty in a spate of horrifying attacks which were found to be the work of one rogue chimp. Nicknamed "Saddam", he was no match for a posse of angry villagers who tracked and shot him, quelling the attacks for two years. Now another killer terrorizes the villages around neighboring Lake Kifruka. The Dark Side Of Chimps is the story of these chimps and what compells them to attack humans. Through the eyes of the local chimp tracker who studied the attacks, and the scientists who watched on in horror, we explore the dark nature of our closest relatives, chimpanzees. What we discover is that chimpanzees are xenophobic, aggressive and violent predators, even towards their own kind, killing not only for meat, but over territory and power.
