Well, pain is the least of my problems. I have been captured before (and it's fun, btw) and I don't think I could endure any pain that could be worse than the last time, and even last time, under pains you will never be able to comprehend, I was silent. Your little, static electricity...stick will hardly pursuade me.
We mean no harm towards citizens. Not all are happy with your Empire. Your Emperor may have brought order, but certainly not equality. What kind of leader, a leader of an entire galaxy at that, takes a dislike toward non-humans? You have certainly not seen what has happened to those not under the protection of the Emperor. As my days as an officer, I certainly got that chance, and left what you call a good thing.
