Rem had the first gun, and she didn't even realize she raised it and flicked off the safety. She wasn't aware that the barrel was loaded and she pulled down the hammer and pulled the trigger on her two darling sons and those bullets pierced their souls. And they'll live--they'll be fine, of course they will. But they'll remember that bullet forever. It's never coming out of their guts, that lead is a part of them now. And that's the curse of being a mother. You can shoot your children and hurt them forever without even knowing. And unlike, say, your mother, or my mother, she didn't have the time to grow old and realize that she shot her children, and come back when she was grey and ailing and say, "God, I am so sorry. I am so, so sorry, and I love you both so, so much. I never should have said those things. I never should have fired." It's too late, it's too late. Having to prevent the fall of man was the undue punishment for all of it. Then, she had to watch Eden crumble from Purgatory.
