Remember that airline baggage handler who was fired for refusing to load an emaciated dog which had body wounds and bloody paws? Although it turned out the canine had not been abused, a vet spoke up for the baggage handler and she was rehired.
But the baggage handler's action touched Fio to the core, first because the woman actually cared--this is a person who would hide Anne Frank from the Nazis. Second, because it's something Fio would do--defy "authority" for the sake of what is right.
That's the essence of your Fio, erring by action rather than inaction. All her sins are those of commission rather than omission. It gets her in trouble, but she'd rather be the kind of person she is than someone who sets up a lawn chair and watches as the cattle cars are loaded.
