I felt that the film treated him very compassionately, and left the opinion of him "neutral." -- i thought that this was good.
what i took away from it was that we all make our decisions -- for good or ill in the end -- and that there's no wrong in them either way. Yes, our decisions hurt people, or edify people, or neither, and that at the end of the day, we are simply human beings being human.
for me, the film brought a great sense of absolution, as i'd been through a couple of difficult family deaths in short order during that time. i felt that i hadn't done enough, or that i could have done more or been better. but, that isn't necessarily true, nor even necessarily "necessary." so, for me, that's what the whole thing brought up.
but, i have to say that another take away is to learn well before you take something big on. he hadn't hunted before, for example, or foraged. it's best to have practical experience with someone experienced before you take it on by yourself. book learning really only goes so far.
