“The perfect being, huh? There is no such thing as perfect in this world. That may sound cliché, but it’s the truth. The average person admires perfection and seeks to obtain it. But, what’s the point of achieving perfection? There is none. Nothing. Not a single thing. I loathe perfection! If something is perfect, then there is nothing left. There is no room for imagination. No place left for a person to gain additional knowledge or abilities. Do you know what that means? For scientists such as ourselves, perfection only brings despair. It is our job to create things more wonderful than anything before them, but never to obtain perfection. A scientist must be a person who finds ecstasy while suffering from that antimony. In short, the moment that foolishness left your mouth and reached my ears, you had already lost. Of course, that’s assuming you are a scientist”

“For me, life and death are very important themes. There is no life without death. That's why it's very important to me.”

“All living things believe in someone superior to them, and cannot live unless they blindly follow them. Then, the objects of their faith try to escape this crushing pressure by seeking another being that is more superior to them to believe in. And they, in turn, seek a stronger being still. That is how all kings are born. That is how... all gods are born. –Aizen”

“Whats the difference between a king and his horse?I dont mean some kiddy shit like one has 4 legs and the other has 2, or ones a person and ones an animal. If their form, ability, and power is exactly the same, then why is it one becomes the king and controls the battle and the other one becomes the horse and carries the king? There's only one answer...INSTINCT!!!”

“In this world, perfection is an illusion. Reagrdless of all those who utter the contrary, this is the reality. Obviously mediocre fools will forever lust for perfection and seek it out. However, what meaning is there in perfection? None. Not a bit. ...After perfection there exists nothing higher. Not even room for creation which means there is no room for wisdom or talent either. Understand? To scientists like ourselves, perfection is despair. - Kurotsuchi Mayuri (Bleach 306)”
