Although the entire book is horrific in its cold detachment, the ending was truly terrifying. Only non-fiction has ever scared me more. Although it's been several months since I've finished the book, one or two scenes are still the stuff of my nightmares. I am completely ambivalent about this book, on one hand wishing I hadn't read it, and on the other relishing it. It definitely makes the reader explore his/her own beliefs about good and evil, and the existence of absolute evil.
