Sam: I guess what I don't understand is why you aren't dying to know all about who you are.
Daniel: I am... and I'm not.
Sam: See, it's the "not" part that—
Daniel: What if I don't like who I was? What if I don't want to be that person? What if I don't have it in me to make up for something I've done wrong?
Stargate SG-1, "Fallen"
"Do you know what it's like to wake up one day and discover you're a monster, a murderer? What if I had died, never knowing what I had been. How can I confess my sins to God if I don't even know what they are?"
— Brother Edward, Babylon 5, "Passing Through Gethsemane"
Ling: What have you done, Greed? Are you determined to prove you're a monster? What kind of sick creature... would kill his own friend!
Greed: He wasn't my friend!
Ling: Then why do you remember him? And are you going to try and tell me Bido was making everything up?
Greed: Those are the last Greed's memories! They're not mine!
Ling: Then why are you in so much pain?
