I'll let myself add some reasoning about accusations against Dyatlov. Even if he violated some instructions (it is still not so clear), environment and way operations conducted in SU (and maybe in some modern countries too) implicitly require that. Management requires real results, not obedience to rules and instructions. Senior personnel has to deliver what is expected from them no matter how. But if something goes wrong, negligence to rules will be formal reason to blame. So, there was no evil layman who got himself near top of hierarchy and made evil decisions. All hierarchy consists of people who was installed at their positions for a reason and they do what is expected from them. Otherwise, replacement occurs.
Basically, if you replace in this situation Dyatlov with somebody of same rank, outcomes could be eventually same or even worse.
However, that trait is not unique to Soviet system only. If you look wider, you probably will be able to resemble Volkswagen scandal, Boeing MAX, Fukusima and so on. Boeing case looks clearly as outcome of "just make it fly" decision.
Luckily, it is a pretty recent period of history and many witnesses of it are still alive or died in recent past. You may be interested to see explaination from Dyatlov at first hand: https://www.youtube.com/watch?v=IVthWR4cR1g This interview has been recorded in 1994, year before he died, but I'm not sure if there are English subtitles for it.
