I do agree with you in regards to "airing-out" what appears to be very bad decisions/bad behavior to someone who is probably reading it with a clear mind in a comfortable chair. From my experiences in the military (nowhere near as nuts as what was going on on Everest), I know people can start doing things that seem otherwise irrational or selfish.

For myself however, who has no aspirations to do anything more technical than Mt. Whitney or Longs Peak, I really enjoy getting my hands on any material related to mountaineering. If books like this weren't put out (warts and all) people like me would know very little about what it is like up there, dare I say that many others may never be inspired to greatness (and start climbing).

I think you have to sit back and be fairly skeptical/critical of anything you read. It is something that can be very difficult for many, including myself. So long as you do that, I encourage others to put their experiences out there to read.
