I got exactly the opposite feeling. A group of inexperienced mountaineers are carried up to the peak, but the amount of tourists and a burning desire to get to the top no matter what result into tragedy. 

To me, the book is more about hybris than heroism. 

The narrator is one of the few capable mountaineers, and this is part of why he survived (and, yes, it was partly luck).

I do agree it's a fantastic book though.

I'm with you on the frustration of the inexperienced tourists being carried up, I found myself getting particularly frustrated at Sandy Pittman who had been posting media pieces and carrying heavy equipment to do so and had basically been dragged up the mountain, you could sense the nervousness some of the more experienced climbers felt about her being on the mountain.
