Have you been indoctrinated with the myth of the noble savage?
____________
The significance of warfare varied tremendously among the hundreds of pre‐Columbian Native American societies, and its meanings and implications changed dramatically for all of them after European contact. Among the more densely populated Eastern Woodland cultures, warfare often served as a means of coping with grief and depopulation. Such conflict, commonly known as a “mourning war,” usually began at the behest of women who had lost a son or husband and desired the group's male warriors to capture individuals from other groups who could replace those they had lost. Captives might help maintain a stable population or appease the grief of bereaved relatives: if the women of the tribe so demanded, captives would be ritually tortured, sometimes to death if the captive was deemed unfit for adoption into the tribe. Because the aim in warfare was to acquire captives, quick raids, as opposed to pitched battles, predominated. Warfare in Eastern Woodland cultures also allowed young males to acquire prestige or status through the demonstration of martial skill and courage. Conflicts among these groups thus stemmed as much from internal social reasons as from external relations with neighbors. Territory and commerce provided little impetus to fight.

It’s a myth. All primitive cultures had barbaric practices; fought amongst themselves in nasty ways; practiced torture; often times child sacrifice and etc.
Even the ones of color. If you were ‘taught’ otherwise—you were lied to.
