Farewell Savage

Since the year 2000, there have been several waves of suicides among the indigenous population of the Colombian Amazon. I discovered that the men commit suicide because of love sorrow. Their wives leave them for white men. The latter think that the Indian feels nothing because they do not express themselves in the same way and, in their language, there are no words to describe feelings. Is it possible that a whole people, the Cácuas Indians, do not feel anything?
