Be realistic. She just witnessed two of her colleagues shot dead in front of her and her child. It is a trumatic, horrifying experience. When they turn to her and say give us the code or we will kill you and your child, the normal, human response would be to save the life of your child and yourself. Anyone who thinks otherwise lives in a fantasy world ala Walter Mitty.
This cuts both ways if anyone cares to be honest. HOW could she ‘know’ in making a ‘deal’ with the devil that she wouldn’t be killed EVEN if she opened the door?
i don’t blame her, but try not to disparage those who think this IS the catalyst that allowed these sub-humans entry.
