I may not be old enough to read the book, listen to it on CD, or watch the movie... I say that because I have tried... several times.  This is not a denial thing. It is closer to the same reason I don't eat razor blades under some delusion of a nutritional value from the metal content. Wow that was extreme. The question for me is... when do I voluntarily put boundaries, limits on the amount of violence I "take in" and "normalize" with an ever increasing tolerance in my psyche.
This is not higher brain function stimuli! This is brain stem stuff...that twists trust, safety and compassion responses.  
I think I will substitute INTO GREAT SILENCE. The 3 hour film on the Carthusians... that was met with a profound tender embrace -- everywhere.  Silence of Solitude  Peace, and all good
