Will: I think I hate him.
Hannibal: I envy you, your hate. It makes it easier when you know how to feel.
Will: What... Makes what easier?
Hannibal: Killing.

Will: What do you think about when you think about killing?
Hannibal: I think about God.
Will: Good and evil?
Hannibal: Good and evil has nothing to do with God.

Hannibal: Mason is discourteous. And discourtesy is unspeakably ugly to me.
Will: Are you thinking about eating him?
Hannibal: Whenever feasible, one should always try to eat the rude.
