This is so upsetting. The people did everything right and created a just and creative society. They shared their technology with others and gained mutual advantage. But they were powerless to resist an evil species and became enslaved. What are they supposed to do to gain back their freedom? Why would they ever trust or cooperate with anyone again? Why would anyone believe in anything but force from this example? Does evil always win? Why would they stop being evil if they gain everything and lose nothing? What is the point of pursuing love and beauty if it can all be taken away by monstrous forces of evil?
