Opinions of Dyatlov's acquaintances and friends vary dramatically - some point out that he was a very warm and welcoming person, while others point out that as soon as he became an expedition leader, he turned into an apodictic and repulsive individual. He also triggered a winner’s instinct. Whatever the case may be, researchers point out that Dyatlov's behavior or character in no way affects the analysis of the clues found in the Pass, and adds nothing to the explanation of the injuries discovered on some of the corpses.
