>As Montaigne pointed out, early modern Europeans were at least as cruel toward enemies and captives, they just expressed it in different ways: i.e. via public executions of witches and heretics, or the tortures of the Inquisition and secular courts.

Yes, this was my instant thought. What a naive Eurocentric way to think of history to insinuate that everyone except the Europeans were just barbaric savages who killed and devalued life. As if the Europeans weren't fresh off their own multi-year killing sprees for this and that reason that equally would have baffled Native Americans.
