I think that the Fanciscans are a tid bit of both.
They are good because they helped the natives learn to use plows so that they didn't have to do it by hand and with sticks. They also converted most of the indians to Catholics.
But they were bad because when they conveted the natives the stopped doing all of their awesome traditions. Another reason the are bad if the indians didn't react peacefully the Franciscans would either kill them or the would take them as slaves.
So the Franciscans weren't exactly peachy keen, but they weren't completely evil .
