How would you interpret "The Bear" by Galway Kinnell?

I read the reviews of this poem that called it "one of the greats", etc. It reminds me a lot of Moby , because the story is a man obsessed with chasing down and killing a large mammal. And it's never really clear exactly why he does this, but both works evoke the feeling of a "search through the writing" or a "story made in the telling". The writings portray the questionable pursuit and eventual victory in the killing, while allowing the reader to speculate as to why the whole bloody (pun intended) process was so necessary in the first place. Though both are technically well-written and capture the reader by their graphic portrayal of blood and guts, as well as the identification of the chaser with the chased, the reviews seem to overlook something: the obviously sadistic torture of a large innocent animal. Both writers are caught up in themselves and narcissistically pursuing their writing talents, constantly in wonder of, essentially, themselves. The reason is probably common human weakness to be seduced by ones talents and also a lack of a worldview, philosophy of life, strong life conviction, moral cause, a religion or something that would give them a perspective to see something beyond themselves. Thus they swirl down into the vortex of self-admiration and you find the writer essentially writing about themselves and the writing process, because their outlook is essentially become an "inlook". Having read both works, I am ashamed to say I was seduced by the elements designed to seduce me. Yet I say, two thumbs down. There are too many crises and realities in this world that require our best attentions to end suffering and poverty and war to spend your life an artistic egoist.
