Read an article in DISCOVER magazine "Why Men Kill" By Marg Roach. An anthropologist, John J. Patton, has been studying the Achuar Indians of Ecuador. They have, by one count, the highest murder rate in the world. War and fighting are inbred into them. One part I found interesting was their definition of warriorship:
"The Achuar concept of warriorship encompasses not only strategy and skill but also valour, willingness, and lack of hesitation. As Patton puts it, 'There's a big difference between hitting the target and hitting the target when the target is trying to hit you.' Wisdom also plays a part. 'In talking to people about this, one of the things that kept coming up was that a good warrior was mas pensativo -- he's more thoughtful.' A good warrior knows when to fight and when not to, whom to pick on and whom not to."
