Ra's al-Ghul

Crime can not be tolerated. Criminals thrive on the indulgence of society's understanding.

Create enough hunger and everyone becomes a criminal.

You have sacrificed sure footing for a killing stroke.

You have learned to bury your guilt with anger. I will teach you to confront it, and to face the truth. You know how to fight six men. We can teach you how to engage six hundred. You know how to disappear. We can teach you to become truly invisible.

— You're vigilantes.
— No, no, no. A vigilante is just a man lost in the scramble for his own gratification. He can be destroyed, or locked up. But if you make yourself more than just a man, if you devote yourself to an ideal, and if they can't stop you, then you become something else entirely.
— Which is?
— Legend, Mr. Wayne.

Criminals thrive on the indulgence of society's understanding.
