By his own admission, Chapman was a self-professed nobody, upset with his lot in life, and was looking to lash out at somebody famous. By killing Lennon, Chapman attained status as somebody (namely, "the guy who killed John Lennon"). In an odd way, reading this book only feeds into the attention Chapman craves. I wouldn't say this book is necessarily "pro-Chapman". Using Chapmans own words via interviews and in print form, the material within the book portrays Chapman (to me) to be every inch of the nobody he felt himself to be. There's really no deeper explanation to be found behind the assassination of John Lennon and the reasons why it happened are made abundantly clear; Chapman was exactly what he thought of himself as. A loser. The in-depth probings of the voices inside his head that drove him to do it just illustrate that point in detail, and after reading the book I felt that I was (in an odd way) just giving Chapman a degree of satisfaction, as he was and is little more than a child in a man's body content with receiving negative attention rather than none at all.
