Ulquiorra Schiffer — memorable quote from Bleach

“You are fighting out of obligation, not out of hatred. You will never reach me like that. Battle without hatred is like a bird without wings. You’ll never defeat anyone like that. You powerless friends are just weights that will break your legs.”

“(To Ichigo Kurosaki) You are a fool, Ichigo Kurosaki. You willingly seek to challenge an opponent so much more powerful than you that it strikes a primal fear into your being. Incomprehensible. If this is the work of the 'heart' that you people speak of, then it is because you possess this 'heart' that you humans bring hurt upon yourself, because you possess this 'heart' that you lose your lives”

“That's right... This world... is cruel. It hit me that living was like a miracle.”

“You find a glimmer of hope, only to lose it. That is when your despair tastes the most divine.”

“Hope is harmony. A just heart, moving toward the light. That is all. Despair is hope's polar opposite. It is messy and confusing. Despair swallows up love, hatred, and everything else. Because not knowing where you will end up is despair. Despair is what even you cannot predict. Only despair's unpredictability will save you from a boring future.”
