I read that a couple of months ago - I agree, absolutely terrifying, and incredibly important.
At the risk of sounding pretentious, lately I've been revisiting Homer's Iliad. We think of it as the sort of dusty old thing they make you read in freshman English class, but really it's a ripping yarn and very readable. One aspect of it that really is gripping me is how Homer humanizes the characters, in an interesting way. They have no internal monologue; no character ever debates in his own mind what he should do. Instead, that kind of thing is all externalized; a deity sweeps down from Olympus to urge a hero into action when he hesitates or to stop Achilles from killing Agamemnon, etc. But what he does instead is that he tells you who everybody's parents are, where they're from and what they were known for there. And he does it in a really poignant way, even for very minor characters who are only introduced very briefly before getting slaughtered by Diomedes or whoever. The cumulative effect, all these lively, promising folks cut down not like so many faceless orcs but human beings who will never return to their beautiful homes and families, is very tragic and powerful.
