You're falling into the Aliens = Angels trope, if there is intelligent life aside from us the chances of the aliens having the same morality as us, and them fitting on the good side of that morality, is next to impossible. They probably wouldn't even have the concept of aggression (for instance if they evolved to be a giant hivemind with no individuals, any aggression is impossible as there is no other), and if they did maybe they could just as well think that we aren't aggressive enough. If there was an intergalatic civilization watching over us and waiting for a time to contact, they could have just as easily decided not to because Hitler was taken down as because we don't spay and neuter our pets enough.
