" LUCIFER: They say what they must sing and say on pain
Of being that which I am and thou art--
Of spirits and of men.

CAIN: And what is that?

LUCIFER: Souls who dare use their immortality,
Souls who dare look the omnipotent tyrant in
His everlasting face and tell him that
His evil is not good! "

― Lord Byron , Cain a Mystery
