Grand Moff Tarkin
Surprised he’s on this list? You shouldn’t be. Tarkin is one of the most ruthless and diabolical characters of the entire franchise. This is a man who manipulates, murders his own people (Scarif), and destroys entire planets to make a point. If you crossed Tarkin, you would find yourself betrayed, or worse, dead in dastardly ways. Even Vader obeyed him. “Fear will keep the local systems in line.” That it will.
