Valuing freedom (even in limited spheres) more than human lives is a pretty familiar American idea. For example, recall Patrick Henry's "give me liberty or give me death" and consider that he was talking about the prospect of being taxed without his consent, not enslavement. Also, recall Private Eightball from Full Metal Jacket:

"Personally, I think, uh... they don't really want to be involved in this war. You know, I mean... they sort of took away our freedom and gave it to the, to the gookers, you know. But they don't want it. They'd rather be alive than free, I guess. Poor dumb bastards."
