Angel 2: God cast you out of Heaven.
Lucifer: And who do you think spread that tabloid headline? It was Captain G, the Eternal One. And why? Because I didn't buy in to his obsessive, compulsive love for mankind.
Angel 1: Mankind is His creation.
Lucifer: Oh, come on! It's not like he invented the Prius, which actually works. I don't have to tell you people what a mess mankind is: the Salem Witch Trials, Third Reich, Twin Towers. Sure, every once in a while, he'll send down a plague to straighten them out, but it's nothing permanent. Humanity brought us Hiroshima and got a re-do. I merely questioned his priorities, and I got the boot.
Angel 2: He said you're evil.
Angel 1: Incarnate. E-Evil incarnate.
Lucifer: It's marketing. He's creating a need in the consumer's mind. Can't be a Super Savior if you don't have a Super Villain.
