Grand Moff Tarkin
He allows the Rebels to escape the Death Star with the Princess after placing a tracking beacon on the "Millennium Falcon" in order to find the Rebel base. He orders the Death Star to destroy the Rebel base on Yavin IV. In the film's climax, Tarkin refuses to believe that the Death Star is in danger from the Rebel starfighter attack. As such, he refuses to evacuate. Subsequently, he is killed when Luke Skywalker succeeds in destroying the Death Star.
