"—And though the enemy brought great numbers to the field of battle, for every number, there is a negative. Their strength became my own. Their minds became my own. All flesh is my flesh. None move, save I will it. This is the rule the Sith were promised, and I have made it real!"
-Karness Muur
"The Sith Empire will burn brightly, like a supernova, dwarfing the complacent Republic. We shall hold the entire galaxy in our grasp."
―Naga Sadow
"The dark side offers power for power's sake. You must crave it. Covet it. You must seek power above all else, with no reservation or hesitation."
"The Force will change you. It will transform you. Some fear this change. The teachings of the Jedi are focused on fighting and controlling this transformation. That is why those who serve the light are limited in what they accomplish. True power can come only to those who embrace the transformation. There can be no compromise. Mercy, compassion, loyalty: all these things will prevent you from claiming what is rightfully yours. Those who follow the dark side must cast aside these conceits. Those who do not—those who try to walk the path of moderation—will fail, dragged down by their own weakness."
"The Sith must be ruled by a single leader: the very embodiment of the strength and power of the dark side. If the leader grows weak another must rise to seize the mantle. The strong rule; the weak are meant to serve. This is the way it must be."
―Darth Revan's holocron
"Wipe this pathetic planet from the face of the galaxy!"
-Darth Malak
"I will not be contained. I cannot be redeemed. Death is all that remains, and you will not kill me. [...] I will not be your trophy. If I must die, I choose how—and everything dies with me."
-Emperor Vitiate
"The scent of your fear is…intoxicating…"
-Darth Phobos
"...As my Force talents grew, I became hypersensitive to the mere existence of others. It was debilitating. No one could help. In the end, there was only one solution...a Sith solution. I learned I could strike out against the pain by snuffing out the bright lights in my mind, one by one. Every death provided relief. I even found joy. I learned how to make others run toward destruction by channeling the misery around them. And I made so much misery."
―Odion
"I'm Lord Daiman. There are no other living beings."
I was bored—and so I created the universe. I have no direct knowledge of the time before time. But I infer that wherever I was, nothing could challenge me. And so I created a new existence. All matter, all energy are manifestations of my undying spirit. But while I gave all beings motion, not all beings serve me. For I also created an opponent -- in Odion. He claims he is my older brother -- But I, of course, have no kin or kind. He is simply what I must overcome to advance."―Daiman
"The forces who favor anarchy over structure have won. For what is this 'democracy' they speak of if not the absence of order? Of reason? Surely the strong should rule—for that is nature's way."
- Lord Kaan
"You must begin by gaining power over yourself; then another; then a group, an order, a world, a species, a group of species… finally, the galaxy itself."
-Darth Plagueis
"Those who ask for mercy are too weak to deserve it."
-Darth Bane
"Fear. Fear attracts the fearful… the strong… the weak… the innocent… the corrupt. Fear. Fear is my ally."
―Darth Maul
"What do you want? Tell me what you want and I will show you how the dark side can help you achieve it. Do you want friends? The dark side can compel them for you. Lovers? The dark side understands passion in a way you never have. Do you want riches—endless life—deep wisdom…?"
-Darth Tryannus
“Long have Sith Empires been built upon the backs of slaves.”
"Beings believe what you tell them. They never check, they never ask, they never think. Tell them the state is menaced by quadrillions of battle droids, and they will not count. Tell them you can save them, and they will never ask—from what, from whom? Just say tyranny, oppression, vague bogeymen that require no analysis. Never specify. Then they look the other way when reality is right in front of them. It's a conjuring trick. The key is distraction, getting them to watch your other hand. Only single-minded beings don't join in the shared illusion, and keep watching you too closely. Single-minded beings are dangerous. And they either work for me, or they don't work at all."
"You want this, don't you? The hate is swelling in you now. Take your Jedi weapon. Use it. I am unarmed. Strike me down with it! Give into your anger! With each passing moment, you make yourself more my servant."
-Darth Sideous
"Even death kneels before me!"
"Of all the monsters I have created, I still regard Darth Vader as something of a minor masterpiece. No, he was not an entirely alchemical creation, but he was my monster nevertheless. Even though he failed to live up to his full potential, there was much pleasure in transforming Anakin Skywalker from a bright-eyed, tousle-headed youth into the greatest Jedi killer of all time. Yes, he ultimately turned against his Master, as monsters sometimes do, but that was my fault, not his. Given the opportunity to create Vader again, I would, and with zeal."
-Reborn Palpatine.
"Sometimes, things must be broken in order to be rebuilt. As I have bent the Force to my will, so I will bend the galaxy and it will know order. My true work is about to begin."
"The Galaxy must experience the pain of death and rapture of rebirth as I have. I will bring chaos. It is time for war."
-Darth Krayt
These sound like totally not-evil people!
