The most thought-provoking tidbit I got from this chapter caused me to both ponder it for a moment and then say, "But what now?"
The line I will reference is the last in the chapter, and states "My guess is that as long as people act toward their fellows in exploitative and selfish ways, the vampire will be with us."
I agree with this to an extent. The vampire, a leech-like being, chooses to continue its ways to preserve its undead lifestyle. Perhaps I am not taking it at face value like the author does, but I see much deeper meanings (some of those even he describes) but I see the vampire as a victim, not the victee. (Okay, that is way wrong, but you know what I mean.) I don't think a vampire is the antagonist. But I am getting off topic. (You want real off topic? Look up vampiric behavior versus sexuality or vampires and homosexuality....hysterical!)
My main point from this line is that not everything or everyone "evil" is selfish. Sometimes there can be a persuasive hidden eaning in the actions or comments of a character. Yes, sometimes a vampire is just a vampire, but sometimes there is so much more under the surface.
