Palpatine: The Sith and the Jedi are similar in almost every way… including their quest for greater power.

Anakin Skywalker: The Sith rely on their passion for their strength. They think inwards – only about themselves.

Palpatine: And the Jedi don’t?

Anakin Skywalker: The Jedi are selfless. They only care about others.
