Greg: All they do is try to make up for it. They just can't forgive themselves, you understand? Look, they were doing something awful to the planet and your mother couldn't stand it anymore. She told me that's why she had to turn on her own kind. She gave up everything just to stop what they started here and drive the invading Gems off of Earth.

Steven: So sh-she saved the world, that's good!

Greg: No such thing as a good war, kiddo. Gems were destroyed, people too... In the end, your mother could only save a handful of her closest friends. If it weren't for her shield, man, I don't know.

This either means that humans tried to help the rebels, or they're just the helpless victims caught in the middle of the war.
