Battlestar Galactica, Season 4

Laura Roslin:
What is your guilt about?

Dr. Gaius Baltar:
I have no guilt.

Roslin:
What was your guilt about?

Baltar:
I gave the access codes to the Cylons. They wiped out most of humanity. Of course I didn't know that's what I was doing at the time. And when I realized what I had done, the magnitude, in that moment I was saved. I was loved, by God. Looking back, I think I was rewarded.

Roslin:
Rewarded?

Baltar:
Pythia talks about a flood. Wiped out most of humanity. Nobody blames the flood. Flood is a force of Nature. Through Flood mankind is rejuvenated, born again. I was another Flood. You see, I blamed myself. I blamed myself. But God made the man that made that choice. God made us all perfect. And in that thought, all my guilt flies away. Flies away like a bird.
