It has been a while since I saw the 1982 film but was reminded of my thoughts on it by NEO-NEOCON's post on "Coco".
Spoiler Alert! (Is this really needed for a 30 year old film?)
Sophie arrives at a concentration camp with her two young children (a boy and a girl) and the camp doctor tells her that she can only bring one with her, the other will go to the gas chamber.
I won't say what she does, but here is what I thought she ought to have done:
Sophie: Why should I trust a man who will order a child to be killed?
Officer: I do not understand...
Sophie: You tell me that I can choose which one will live and you will honor that choice. Why should I believe you? It is in your power to kill none of us, all of us or some of us. Perhaps I would say, "Save the boy"! and out of perverse pleasure, you will kill him first.
Officer: I will kill both children if you do not pick one.
Sophie: I will not be complicit in your evil. You can choose to kill one, both or neither. This is your choice. I have no reason to believe anything you say and will not cooperate. Even if I did trust you, I think that you may believe that my playing along will dilute your guilt. I will not allow this! You are responsible for our fate.
