Query: What's Kropp's problem?

David Lagercrantz should get more credit for writing this book. I am basing this on the information I read on page 220. The book is a bit heavy handed. Kropp seems like an arrogant person. He had no business talking about how bad another climber's English was especially when he had to enlist help to write this book. Kropp's lack of morals as depicted in the book proves anyone determined enough can climb a mountain. It was interesting only because the protagonist was going somewhere. Endangering one's life just to climb a mountain is stupid.
