Quote #4
TARKIN: You would prefer another target? A military target? Then name the system. I grow tired of asking this, so it will be the last time. Where is the rebel base?
LEIA: Dantooine. They're on Dantooine.
TARKIN: There. You see, Lord Vader? She can be reasonable. Continue with the operation. You may fire when ready.
LEIA: What?
TARKIN: You're far too trusting. Dantooine is too remote to make an effective demonstration, but don't worry. We will deal with your rebel friends soon enough.
LEIA: No!
If you thought Vader was evil, get a load of Tarkin. He blew up an entire planet simply to prove that he could blow up an entire planet. He's what would happen if a Bond villain were elected president. Dude is just evil.
Quote #5
HAN: It is for me, sister. Look, I ain't in this for your revolution and I'm not in it for you, Princess. I expect to be well paid. I'm in it for the money.
LEIA: You needn't worry about your reward. If money is all that you love, then that's what you'll receive.
LEIA [to Luke]: Your friend is quite a mercenary. I wonder if he really cares about anything or anybody.
If any character comes close to toeing the good-evil line, it's Han. His motives are self-centered, but his actions are praiseworthy because he fights with the heroes. For an adventure story like Star Wars, actions are what count.
Quote #6
HAN: You're all clear, kid! Now let's blow this thing and go home!
Was there ever any doubt? Despite being a bit on the fence earlier, Han lands on the side of good. In fact, all the characters in the original trilogy ultimately choose good or evil in the end, no matter how wishy-washy they were before.
