The fact that they killed all the missionaries even after having a nice visit seemed very disturbing and the idea that this behavior is not isolated to Western intruders, but to other tribes and even internally committing brutal acts reeks of inhumanity. Another thing that I find extremely interesting is that in this society everyone is equal. Males have been a dominant figure in human societies throughout the ages, so it's strange that this particular culture is so balanced. These two ideas of balance and lack of hierarchy in a culture in a context of intense savagery seem in conflict. The only parting thought in the film is that the Waorani people understand the need for balance to continue to expect nomadic ways to provide a continuous supply of food and that the outside world is exploiting the resources of their rainforest, thus threatening their way of life. After seeing the film and reading about them through Davis' prism, their culture seems to be an enigma...
