Hannibal [Season 2, Episode 8]

An abnormal reaction to an abnormal situation is normal behavior.

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: I discovered a truth about myself when I tried to have you killed.
Hannibal: That doing bad things to bad people makes you feel good?
Will: Yes.

Many troublesome behaviors strike when you are uncertain of yourself.

Margot: They think I'm weird.
Hannibal: I'm much weirder than you will ever be, Margot. It's fine to be weird.
