Life of Pi: Page 301 to End

I found the ending of this book to be simultaneously disgusting and depressing. Only now do we truly find out why this was such a bad experience which scarred him for years. Pi, the cook, Pi's mother and the sailor all represent the animals. The cook kills the sailor and Pi's mother, and participates in cannibalism. Pi gets revenge (as Richard Parker attacking the french cannibal) by stabbing the cook, and eats pieces of the human flesh. After the shocking story, Chiba and Okamoto are surprised, and finally inquire after the possible causes of the sinking of the Tsimtsum. They end up leaving, and the report only covers the lack of hard evidence and their choice to believe the animal version of Pi's story when th elast line of the book is "...and non in the company of an adult Bengal tiger."
