Aizen Sousuke — 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.”

“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.”

“Jojo, being human means having limits. I've learned something. The more carefully you scheme, the more unexpected events come along”

“We ruin the countries we govern and the people in our care. We slaughter our enemies and sacrifice all our allies. We’ll keep killing till there’s nothing left but to destroy ourselves. It will never be enough.”

“As a human, what kind of achievements will you leave behind? I bet you'll leave behind a legacy as a psychotic killer, and that thrills me!”
