There is a movie called "Black Robe" in which a French priest travels with some Indians to a mission in the wilderness. Relationships between the natives and Europeans were complex. It was brought up that the Indians would trade captured Frenchmen to the English or Dutch for weapons. In turn I would guess that the English and Dutch would sell the French back to France.
It seemed the the church had good intention's but it was the Indians destiny to lose the New World to the Europeans due to lack of technology and old hatreds between tribes.
Same old story throughout mankind's history.
The same is true of the British Raj in India as well: Better technology and ancient, deep rooted hatred between not only tribes/princelings, but between religious groups as well.
