"The dark side of the Force is a pathway to many abilities some consider to be — un-natural..."
— Supreme Chancellor Palpatine
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.
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: (speaking from the gut, using his infamous rasping voice) I AM the senate!
Windu: Not - yet.
"Once more, the Sith shall rule the galaxy! and we shall have... peace."
— Darth Sidious
Obi-Wan Kenobi: It's over Anakin, I have the high ground!
Anakin Skywalker: You underestimate my power!
Obi-Wan: ... Don't try it.
Anakin: RAAAARGH! (Force leaps at Kenobi, his master takes his saber in both hands and cuts his former pupil's legs off at the knees and his left arm at the shoulder while he's in mid somersault. With a hideous moan, the fallen Jedi crashes onto the volcanic earth and slides down the incline to halt just before the lip of the lava river; crying and gnashing in helpless fury and despair)
Obi-Wan: (deactivates his saber and clips it to his belt, all the while looking down at the maimed murderer and war-criminal, whose eyes are now the amber iris and red limbus circle of Dark Side corruption in his agony) YOU WERE THE CHOSEN ONE! IT WAS SAID YOU WOULD DESTROY THE SITH, NOT JOIN THEM! ... BRING BALANCE TO THE FORCE! NOT LEAVE IT IN DARKNESS! (picks up Anakin's lightsaber, a memento of the hero of the Clone Wars, as well as the butcher of children, he begins to leave but turns back as the mutilated would-be-Sith-Lord utters a chilling howl that promises retribution)
Darth Vader: (screaming until his throat seems fit to rip) I HATE YOU!!!
Obi-Wan: (with infinite sadness and a spark of tenderness) ... You were my brother, Anakin. ... I loved you.
Vader: (the Sith's mask of eternal enmity cracks for a second in astonishment but the long grueling battle and his terrible wounds catch up to him and his Force shield drops causing the lava's sheer heat from the flow's proximity to set his clothes alight and work their way up his body, engulfing him in flames. He screams blue murder as he sinks into the ash, his body being seared, melted and charred beyond recognition. His flaming skeletal cybernetic hand reaches out to Kenobi. We canot tell whether in unbridled rage or in desperation for clemency, he lets out one last choking scream as his lungs are ruptured and blackened from within before his will reasserts itself through, or even due to, the unimaginable pain and he is able to block the combustion through the Dark Side of the Force)
Obi-Wan: (walks away, leaving his failure to die)

"The dark is generous, and it is patient, and it always winsóbut in the heart of its strength lies weakness: one lone candle is enough to hold it back. Love is more than a candle. Love can ignite the stars."
