The argument was valid even before the hike started, since Zina Kolmogorova letter to Lidiya Grigoryeva of January 22, 1959 :
"The group is ok, I don't know how will it be the moment we go. Will we quarrel. After all, Kolevatov is with us."
You are right to consider carefully the psychological aspect of the documents that we have.

We can reasonably imagine that the 9 hikers were energetic and courageous people but with a rather bad temper.
Especially Dyatlov who was very authoritarian and often unpleasant and awkward in human relations.
There were probably quarrels, sharp verbal oppositions...etc. But that is not unusual in this kind of expedition. And I think that you are going down the wrong path of research when you attribute too much importance to the word quarrel, the exact meaning of which is unclear.
Dyatlov and Zolotaryov seem to disagree, Kolevatov is perhaps slightly worried.
Zolotaryov, Doroshenko, Dyatlov seem to feel some resentment, or are they just tired?
The route planned for this winter hike with poor equipment was not very difficult, but it still required constant attention. An unforeseen complication (broken ski, lost useful accessory, frozen foot....etc) could lead to failure, i.e. at least a pitiful premature return.
In the event of a real danger arising unexpectedly, in this somewhat impressive wilderness atmosphere, internal dissension immediately takes a back seat.
Each member of the group feels that in order to win or survive it is better to postpone the arguments for the time being, so that they can regroup and fight together most effectively.
This group behaviour is usually seen on all ships isolated on the open sea. The crew, sometimes disunited in good weather, comes together and cooperates without problems when the storm arrives.
Indeed the sentence :
After all, Kolevatov is with us.
Nothing in what we know of the tragic aftermath suggests a clue to suspect Kolevatov
of being a particular cause of conflict.
I even wonder whether Kolgomorova might have made a mistake and falsely written Kolevatov instead of Zolotaryov ! ?
Indeed I think that Zolotaryov could have played an informant role to the CPSU with the mission to describe and report the opinions and political sensitivities of the hikers (considered to be future cadres or notables).
Perhaps with a special focus on Thibeaux-Brignolle (Tibo) whose father Vladimir Iosifovich had died in September 1943 as a result of his stay in various Gulag camps.
Zolotaryov and Tibo: what do these 2 pictures inspire you?
Personally I am slowly building my TOKEB theory particularly inspired by 2 remarks of psychological nature.
1) the spectacular transformation of Dubinina's personality after the passage to Vizhay.
See Lyudmila Dubinina's premonition of her tragic death: https://forum.dyatlovpass.com/index.php?topic=433.0
and BottledBrunette's intuitionhttps://forum.dyatlovpass.com/index.php?topic=433.msg6905#msg6905
It was not a supernatural or magical premonition that troubled Dubinina but a keen intuition that the conflicts, which we can only guess at, with some of the hostile people of Vizhay, could lead to a dramatic and terrifying outcome.
After leaving Vizhay on 26 January, only the three most experienced and politically mature hikers (Zolotaryov, Kolevatov, Tibo) did not completely disregard Dubinina's worrying intuition. The other five found this concern ridiculous and stupid and perhaps even openly laughed.
2) The separation of the group proved by the scattering of the corpses as they were found by the rescuers.
As a result, after the suffocating exit from the tent on 1 February at the cedar and fire, there was great confusion among the hikers.
What is going on? This suffocating gas is incomprehensible and mysterious!
Zolotaryov, Kolevatov, Tibo said: this is not a joke. A mortal danger exists and they built 4 beds of branches to be able to stay hidden for a long time in the Den.
The others - were there 5 or only 3? (Kolgomorova and Slobodin remained inanimate during the descent-) having remained more vulnerable, as they were more visible near the fire, were more quickly massacred........
