Seems a good enough place to trot out my other interpretation (that I do not necessarily hold to) of that scene.

It could be rather more immediate (selfish, even, though I hesitate to use the word). Less realizing Adam is a monster, and more not wanting to kill innocents personally. Adam tells her to "move up to the next car." That is, to work forward, toward more occupied areas of the train. Therefore, her question about the crew and Adam's response might suggest that he expects her to secure the next car by killing any crew she finds. Therefore, it may be less concern over the lack of regard for collateral damage and more the expectation of her personally slaughtering defenseless train crew.
