When the Galactic Empire killed two billion on the planet Alderaan, there was a of both-sides-do-it rhetoric in the public discourse afterwards. The rebels also kill people, even shoot them and they have Y-wing ships that drop actual bombs. “Surely they would blow up Coruscant if they could”, they were saying on debate shows.
Both sides do it, but one side does it a heck of a lot more and is killing twenty times more people in the most brutal conflict in modern galactic history. To me, that does matter. Intent isn’t everything, actual actions and results matters a lot too.
Why? Because with great power there must also come great responsibility.
