There's a scene where the film's narrator/director listens to the audiotape of the attack with headphones on. We see his reactions, and afterwards, he says the tape should be destroyed.
There's a grim fascination. I think this is one of the best movies to come out last year (I missed it in theatres).
The guy was just completely nuts. Unfortunately, his behavior got not only himself killed, but his girlfriend as well as at least two bears.
The guy needed lithium, not tickets to Alaska.
