Quotes / Revenge of the Sith

Supreme Chancellor Palpatine: Did you ever hear the tragedy of Darth Plagueis the Wise?
Anakin Skywalker: No.
Palpatine: I thought not, it's not a story the Jedi would tell you - it's a Sith legend. Darth Plagueis was a dark lord of the Sith so powerful and so wise, he could use the Force to influence the midi-chlorians to create...life. He had such a knowledge of the Dark Side, he could even keep the ones he cared about...from dying.
Anakin: He could actually...save people from death?
Palpatine: The Dark Side of the Force is a pathway to many abilities some consider to be unnatural.
Anakin: What happened to him?
Palpatine: He became so powerful...the only thing he was afraid of was losing his power - which, eventually, of course, he did. Unfortunately, he taught his apprentice everything he knew, then his apprentice killed him in his sleep. Ironic...he could save others from death...but not himself.
Anakin: Is it possible to learn this power?
Palpatine: Not from a Jedi.

General Grievous: You Fool! I have been trained in your Jedi arts by Count Dooku.
Obi-Wan Kenobi: It's funny you should mention that. I trained the man who killed him.
— The novelization

Mace Windu: In the name of the Galactic Senate of the Republic, you're under arrest, Chancellor.
Supreme Chancellor Palpatine: Are you threatening me, Master Jedi?
Windu: The Senate will decide your fate.
Palpatine: I AM the Senate!
Windu: Not yet.

"Once more, the Sith shall rule the galaxy! And we shall have... peace."
Darth Sidious

Darth Sidious: Commander Cody. The time has come. Execute Order 66.
Cdr. Cody: Yes, my Lord. BLAST 'EM!

Anakin Skywalker: You've turned her against me!
Obi-Wan Kenobi: You have done that yourself!
Obi-Wan: Your anger and your lust for power have already done that. You have allowed this dark lord to twist your mind, until now... you have become the very thing you swore to destroy.
Anakin: Don't lecture me, Obi-Wan. I see through the lies of the Jedi. I don't fear the dark side as you do! I have brought peace, freedom, justice and security to my new Empire!
Obi-Wan: Your new empire?
Anakin: Don't make me kill you.
Obi-Wan: Anakin, my allegiance is to the Republic. To democracy!
Anakin: If you're not with me... you're my enemy.

Obi-Wan: It's over, Anakin. I have the high ground!
Anakin: You underestimate my power!
Obi-Wan: ...don't try it.

Obi-Wan: YOU WERE THE CHOSEN ONE! You were meant to destroy the Sith, not join them! Bring balance to the Force, not leave it in darkness.
Anakin: I HATE YOU!
Darth Sidious: Lord Vader. Can you hear me?
Darth Vader: Yes, master... where is Padmé? Is she safe? Is she all right?
Sidious: It seems, in your anger... you killed her.
Vader: I... I couldn't have. She was alive! I felt it!
(Vader, through the Force, destroys the equipment of the laboratory he's in)
Vader: NO!!!

You can hear yourself breathing. It comes hard, and harsh, and it scrapes nerves already raw, but you cannot stop it.
You can never stop it. You cannot even slow it down. You don't even have lungs anymore.
Mechanisms hardwired into your chest breathe for you. They will pump oxygen into your bloodstream, forever.
The novelization, on Anakin's rebuilding

You remember the dragon that you brought Vader forth from your heart to slay. You remember the cold venom in Vader's blood. You remember the furnace of Vader's fury, and the black hatred of seizing her throat to silence her lying mouth—and there is one blazing moment in which you finally understand that there was no dragon. That there was no Vader. That there was only you. Only Anakin Skywalker.
That it was all you. Is you. Only you.
You did it. You killed her.
You killed her because, finally, when you could have saved her, when you could have gone away with her, when you could have been thinking about her, you were only thinking about yourself... it is in this blazing moment that you finally understand the trap of the dark side, the final cruelty of the Sith—because now your self is all you will ever have.

And you rage and scream and reach through the Force to crush the shadow who has destroyed you, but you are so far less now than what you were, you are more than half machine, you are like a painter who has gone blind, a composer gone deaf, you can remember where the power was but the power you can touch is only a memory, and so with all your world-destroying fury it is only droids around you that implode, and equipment, and the table on which you were strapped shatters, and in the end, you cannot touch the shadow.
In the end, you do not even want to. In the end, the shadow is all you have left. Because the shadow understands you, the shadow forgives you, the shadow gathers you unto itself—and within your furnace heart, you burn in your own flame.

This is how it feels to be Anakin Skywalker, forever.
The novelization, on Anakin's Heel Realization
