Ahsoka Tano: Do you believe what they said, Master, that a Jedi could do this?

Anakin Skywalker: Not every Jedi agrees with this war, Ahsoka. There are many political idealists among us.

Ahsoka Tano: But a traitor?

Anakin Skywalker: I'm afraid one can eventually become the other. Remember Count Dooku and General Krell. That's how they started too.
