The best example of greed and warfare among Indians would probably be the Iroquois’s “League of Five Nations”

If you look around you will see that Indians did possess traits of materialism and war.
"Another effect of the horse on the Plains Indians is that it increased intertribal warfare as a symbol of wealth and an object of war. Many tribes described the stealing of another tribe's horses as an honorable feat. In relation to war, horses were valuable because warriors found it easier to attack their enemies that were too far away to capture on foot. Horses also stemmed tensions over the control of the most useful hunting grounds and gave the Indians more time to rest and relax. Before the horse, the Indians spent much of their time planning the wars, fighting the wars, and celebrating their victories of the wars." [url]http://www.artsci.wustl.edu/~cmkurpie/war2.html [/url]
"In eastern Oregon, warfare was more constant and more dangerous. The Paiutes and Bannocks pressed against the Nez Perce, Cayuse, Umatillas, Klamaths, Modocs and Warm Springs Indians. There was constant conflict in the territory as the tribes competed for hunting grounds, and additional wealth in the form of horses and slaves. The coming of the white man added to this turmoil."

"The first U.S. treaty the Wisconsin Ojibwe signed was in 1825 at Prairie du Chien, Wisconsin, involving the Ojibwe and other Great Lakes and Midwestern tribes. Some of these tribes fought wars amongst themselves, and the United States wanted to end their disputes by establishing boundaries between the tribes. In particular, the Ojibwe and the Santee Dakota (also called the Santee Sioux) had fought for possession of northern Wisconsin and Minnesota for over a century, and thus a boundary line was established between them."
