Quote from : White Night Book

Anger is just anger. It isn't good. It isn't bad. It just is. What you do with it is what matters. It's like anything else. You can use it to build or to destroy. You just have to make the choice." Constructive anger," the demon said, her voice dripping sarcasm. Also known as passion," I said quietly. "Passion has overthrown tyrants and freed prisoners and slaves. Passion has brought justice where there was savagery. Passion has created freedom where there was nothing but fear. Passion has helped souls rise from the ashes of their horrible lives and build something better, stronger, more beautiful.
