Quotes by Yoshimura from Tokyo Ghoul
...The act of taking is equally evil. We, from the moment of birth, continue to take. Food, connections, even fellow blood. Living to utmost. Continuing to slaughter, kill, take. Life is to constantly sin. Life is evil itself. I am aware I am evil... And so are you all. Now, come kill me. And I shall do the same!
It's not because we can't take vengeance that we should feel sorry. The real reason to feel sorry... is when one is hung up on revenge and can't live their own life.
