"men confronted apex predators on a point of honor". Give me a break, maybe for the rush, or to gain a rep or make a buck or because that was part of their adaptation to their environment. Societies rewarded successful hunters because they provided, good earners get more rewards.

Outside of the social insects humans are about the only species where members of the group, especially males, routinely and voluntarily place themselves in extreme danger often to the point of death to protect the members of their social group.
You can believe that Indians in particular and/or all humans over the last 100,000 years had no sense of honor if ya want.
