They were not even turning around to face the danger that made them leave the tent."
I've never heard anyone mention that detail before! That in combination with them walking three abreast through the deep snow so they could talk to each other is very strange thing to do after cutting your way out of the tent and leaving it without shoes and proper clothing.
The only reasons to abandon the tent in such a manner is either by force or because the tent was inaccessible. Nothing else makes much sense, because why not take a couple minutes to grab shoes and coats if you can walk down slope calmly discussing the situation? Not turning around to check out the situation at the tent seems to indicate the tent was a no go. But then three of them apparently tried to return to it later. Baffling.
If it wasn't completely ludicrous
, I'd suggest the theory that Dyatlov's leadership was being challenged over some questionable decision making, so he comes up with a survival scenario to prove a point, and his challengers agree to it (which means they all have to go along). Maybe they underestimated the difficulty or distance to the trees. And then an accident occurs in the forest, or strong wind picks up again, dooming them.
But why would a group of experienced hikers seriously propose or accept a suicidal dare? At the very least, they risk losing fingers and toes. Just a dumb theory to illustrate how odd their leaving of the tent seems to be.
