"I want you offended--this book is written as much as possible from the point of view of the predator. You need to be offended by his thoughts. More importantly, you, average citizen, need to be able to spot those thoughts as they are forming in the mind of your creepy next-door neighbor. Or, if you are someone working a sexual homicide case, you need to be able to nail the killer sitting cheerfully opposite you in an interview room."
