If Phrolova is evil, then why is she trying to save people?

Rover wasn't there when Phrolova's village was struck by a meteor
Rover wasn't there when Ouroboros was struck by a meteor
Rover wasn't there when Guixu was struck by a meteor

ROVER. DIDN'T. SAVE. ANYONE.

He was too busy mind wiping himself so he doesn't have to carry the burden of being a fucking failure.
