Sparrow is a Fanatic

"A fanatic is someone who redoubles his efforts when he has forgotten his goal" ~Chuck Jones

This quote that i stumbled upon the other day is incredible, in it's description of Sparrow, and, arguably, others in my story. Sparrow is a fanatic. He keeps trying harder and harder, but he's lost sight of what his goal was: to save people from injustice. Over time, and with pain, he's focused his entire existence into one thing, and that is Irakura. He is a fanatic. All he wants is to overthrow Irakura and destroy him, while he has forgotten that his aim was originally to help people.
