Indians didn’t have war crime trials or even just ‘war crimes’ and the horrors they did weren’t done by renegade men or psychopaths, it wasn’t an aberration that would go down in history as a shame.
The Indians would bring captives into their town so that their families and the entire community could share in and enjoy the days-long torture of people.
The Indian horrors beyond description were celebrated and honored by them and were entertainment and training for the little children and their girlfriends and wives and grandmothers, and their mayors and councilmen.
This was the same way Europeans behaved when they were tribesmen in the forests and plains. Tacitus describes how the Germans tortured captured Romans after Varro’s defeat.
