Cas: I thought you were only killing demons.
Cain: I’ve decided to fix my mistakes of introducing murder.
Cain: By murdering some more.
Cain: Anyone who does anything wrong or is descended from me shall face death
Cas: Wait
Cas: Isn’t that everyone?
Cain: No.
Cain: Like 10% at most.
Cas: It seems like everyone. There were only 3 of you to begin with and you killed 1. I’m pretty sure your descendants have all intermarried by now and everyone else has probably thought about stealing now and then.
Cain: You don’t know that.
Cas: And isn’t this what Lucifer wanted you to do in the first place?
Cain: No.
Cain: Yes.
Cain: That’s not the point. I’m helping humanity.
Cas: I don’t understand your definition of “helping”
Cain: It’s not about what makes sense! It’s about what feels Good!
Cain: To me.
Cas: You know, hearing what you’ve said and standing in a garden of dead bodies.
Cas: I see the resemblance now.
Cain: With who.
Cas: With Dean. Who seems to be trying to do something similar.
Cain: Thanks, Castiel. I’ll just put him on the list.
Cas: Okay, I think I’ve been indiscreet.
