Quote #7
THE EMPEROR: The alliance will die. As will your friends. Good, I can feel your anger. I am defenseless. Take your weapon. Strike me down with all of your hatred and your journey towards the Dark Side will be complete!
The Emperor sure has a one-track mind. He's anger and hate 24/7.
Quote #8
LUKE: Your thoughts betray you, Father. I feel the good in you, the conflict.
DARTH VADER: There is no conflict.
LUKE: You couldn't bring yourself to kill me before, and I don't believe you'll destroy me now.
DARTH VADER: You underestimate the power of the Dark Side. If you will not fight, then you will meet your destiny.
At the center of Luke's goodness is his faith in Darth Vader. He firmly believes that underneath all that evil and that spooky mask, his dad's still a fundamentally good guy.
Quote #9
DARTH VADER: You cannot hide forever, Luke.
LUKE: I will not fight you.
DARTH VADER: Give yourself to the Dark Side. It is the only way you can save your friends. Yes, your thoughts betray you. Your feelings for them are strong. Especially for... sister. So, you have a twin sister. Your feelings have now betrayed her, too. Obi-Wan was wise to hide her from me. Now his failure is complete. If you will not turn to the Dark Side, then perhaps she will.
LUKE: Never!
As this exchange shows, Darth Vader's evil knows no bounds. Can't turn his son to the Dark Side? Fine! He'll just turn his daughter. Suffice it to say, this guy's not winning any Father of the Year awards.
