He rejected his 'Encomienda' (Spanish way of undercovering slavery) and claimed that the only justification for the Spanish to be in America was to spread Catholicism among the natives.

If he changed his manners to them sometimes was only because it was convenient to him, but he never abandoned his initial opinion.
