Master Yoda: Thousands of Jedi once there were. Then came war. In our arrogance, join the conflict swiftly we did. Fear, anger, hate. Consumed by the dark side the Jedi were.
Ezra Bridger: Was it wrong for the Jedi to fight? Is it wrong for me to protect my friends?
Master Yoda: Wrong? Hmm. A long time, fought I did. Consumed by fear I was, though see it I did not.
Ezra Bridger: You were afraid?
Master Yoda: Yes, afraid. Hmm, surprised are you? A challenge lifelong it is, not to bend fear into anger.
