Perhaps. I've just never met one who wasn't self-righteous, at the very least. Thinking they know better, or are better, because of their rigid adherence to their teachings. Even if that adherence might get innocents killed.
My own people are not much better, at least most of those in charge, and are just as rigid in their own rules.
The Sith utilize the Klingon type of promotion; kill the person above you. It makes it impossible to anything for the regular people if you're too busy keeping an eye on your own back. But most Sith only want power and control.
The Empire is failing because of that. We will weaken and topple within while external forces pressure us from without.
I would normally be sorry for ranting at you, but I do enjoy talking.
