Why do we find so much imagery of eating in Canto's 32-34?

                 And then the hunger had more
Power than even sorrow had over me. (ll. 71-72; Canto XXXIII)

In these final Hell-ish moments, the reader experiences various horrific scenes and depictions of cannibalism. What inspired the poet to focus so graphically on the gnawing of flesh. The reader finds so much imagery of eating in Cantos 32-34 because the sin cannibalism breaks all the categories of sin. Dante's first sincontinence. These sinners lack the will to break desires of sin. The cannibalistic are incontinent, they simply cannot help themselves, so they give into the glutinousness of cannibalism. The second sin category are the sins of violence, and to be a cannibal is definitely to be violent. The final category is betrayal. When the cannibals eat each over they are betraying humanity. They are literally eating flesh, which is man's defining quality. They have in a sense betrayed who they are, not to mention the friend or the human they are gnashing upon.
