Kuchiki Byakuya — memorable quote from Bleach

“Are you afraid? You don’t want to die, do you? Not just Abarai, if anyone… acts upon the thought of not wanting you to die, you will suddenly begin to fear your impending death, right?”

“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.”

“Don’t hesitate to cut the enemy. Don’t falter to finish them off. Much less heal their wounds. That’s unspeakable, nino. Leave the chocolate here. Become a demon, nino. As strong as a demon. As wicked as a demon. You have to learn that the only way to stand up against ruthlessness, is to become ruthless yourself.”

“Don’t be so stuck-up. Just enjoy this! Killing and being killed. They are just a way to pass time.”

“Do you know what a scientist fears most in this world above all else? It's oblivion, my friend. A scientist measures our lives in the ways we develop and expand our knowledge through myriad variations. Nothing can take its place. It's our very soul. I have done the worst thing one scientist can do to another: I have altered your thought process. When my drug takes effect, you will find your mind has lost the ability to think.”
