The Inca were easy to conquer because they had no steel and no horses. The Spanish were so unimaginably horrible that I can't imagine their presence having anything other than a uniting effect.
The book "The Last Days Of The Inca" describe a scene were ~20 armored conquistadors are in a town that's surrounded by mountains on all sides. The Incas managed to call in enough people that the hillsides were all completely covered with tens of thousands of people waiting to attack. When they did, the entire population was slaughtered by the 20 conquistadors on horseback (there were so many dead bodies that new waves of attackers had to struggle to climb over them), and the Incas managed to kill only a single conquistador.
If you want to finally abuse yourself of the fairy tale notion that somehow justice will always prevail in the world, I recommend reading "The Last Days Of The Incas."
