What role did Las Casas expect the Spaniards to play on Hispaniola? What did they do instead?

The role that Las Cases expected the Spaniards to play on Hispaniola was to carry them in an incredible way but what happened was that it was backwards. Spaniards, in a matter of seconds, carried on like ravening wild animals such as tigers, wolves, or lions that had been hungry for quite a while, and for forty years they have done nothing else, nor they are in pain. They destroyed them with sporadic and new and jumpers' sort of violence.
