Aizen Sousuke — memorable quote from Bleach

“Very well. Then krieg(German for "war") is what you shall have. We are a clenched fist, ready to strike down all who oppose us with our might. But, after enduring over half a century wallowing in the darkness, for us, a simple, "ordinary" war will no longer be sufficient. We need a massive war! A war beyond any other that man's history has ever known! We are but a single battalion, the remnants of a defeated army numbering less than a thousand strong. However, I believe that each of you old warriors is worth a thousand of their sickly soft children! We represent a force that could easily defeat an army of a million and one men!”

“The world lies! Thou shalt not commit murder, thou shalt not bear false witness, thou shalt not cheat, thou shalt not steal, thou shalt not covet thy neighbor's wife. All of these are lies! Mere illusions and nothing more! They don't want to be killed, they don't want to be robbed, using the twin lies of justice and morality, the weak are endeavoring to protect themselves. But the first truth is that the strong devour the weak, so let us feed upon people, upon wealth, upon riches and power! We, at Britannia, shall feast upon the raw flesh of the world itself! We will crush this deception and bring forth the truth! All Hail Britannia!”

“"If I do this, I can stop the rebellion", "if I do that, I can stop the rebellion"... Open your eyes, princess! Your zealous idealism disgusts me! Ideals can only be spoken by those powerful enough to carry them out. And that excludes you!”

“A skilled dictator is much more beneficial to humanity than a democracy of ignorant people.”

“The vampires don't really care about humanity in general. It's only specific humans like you that concern them... The kind of humans who will stop at nothing to acquire more power.”
