And yet Krakauer had no issues throwing a guy, who tried to save some of the members of his team, under the bus when Krakauer messed up, and turned a hero into a villain.
Jon Krakauer has responded to Anatoli Boukreev here[0], it seems as like most things in life, there is more nuance this than just hero villain dichotomy.
That Kazakh person can't defend himself any longer and Krakauer's story is highly suspicious due to glaring holes/omissions - perfect knowledge of the incoming storm yet deciding to move forward, "hallucinated all the way down" as a defense for not helping Beck Weathers, sleeping in a tent while Anatoli was saving clients, expecting from the barely surviving Kazakh climber a perfect knowledge of English etc. Krakauer is a talented writer writing compelling stories but his throwing mud on a deceased climber who managed to save all his clients in the death zone that night is just disgusting.
This. He writes good, but its kind of accepted in climbing community that he really messed up with Everest disaster, lied, tried to blame others for his own fails etc.
