In any time or era of history and especially in times when the range of a group of homo-sapiens was limited to their ability to walk or travel on horseback we see a deeply rooted attachment to the base level "eco-system" that overrides any morality issues and is indeed a pure ....them or us mentality. If a tribe or culture had lived in a specific land area for as long as their recorded history verbal or written indicated and then required that hunting territory for sustenance they would kill with zero regard to morality in efforts to ensure that ground remained their property. Much like insects or animals defend territory and in turn prey upon themselves with a brutal yet efficient regard for the continuance of their specie or sub group.
Native Americans saw themselves as part of the circle of life as it were. No surprise to them I am certain as to the need to do whatever they could to ensure the survival of individual clans or tribes within a territory. They knew and indeed looked upon killing as a means to keeping what they viewed as theres without regard to any rules of warfare or moral hand wringing. The surival of the fittest as it were.
Do you not think it is still that way today ...even it terms of global interactions?
When attacked or threatened by another culture or sub group we will attack and defend ourselves equivalent to the need to ensure our own way of life continues. Should we fail in that arena we then are not necessarily wiped off the face of the map but we are "changed" irrevocably as the native Americans were changed. Conquer or be conquered is still the way of the world regardless of morality or religious faith or a lack therof at all.
The fact that responsible modern democracies seek only to defend their interests is worthy indeed as opposed to attacking and conquering to expand empires or gain more territory.
