In any situation where you're trying to make a prediction, the best you can do is to make a decision based on available information, and then try to update based on outcomes, but being wrong in retrospect is absolutely not equal to having made a bad choice. It's, frankly, shocking to me how often someone will witness one bad outcome and accuse the person involved of being an idiot and making the obviously wrong choice.
In general, I can't recommend German-language "Berg und Steigen" magazine enough. It's focuses on safety and risk management in mountain-related activities (mountaineering, indoor/outdoor climbing, skiing, ski touring, mountain biking, ...). Older issues become completely freely accessible in their archive [2].

When I was a more active climber, I read it religiously every year. It was very interesting and I definitely learned some important safety lessons I put to good use in my own activities.

Then, the shiteth has hitteth the fan. Socked in for a few days with no weather window. Had to bail, with the summit in reach.
Lesson learned, the mountain will always be there.
'the shit hit the fan' → 'the shite hit the fan'
'the shit hits the fan' → 'the shite hitteth the fan'
'the shit has hit the fan' → 'the shite hath hit the fan'
You could also throw in an archaic alternate spelling of 'hit' ('hitt' or 'hitte') or 'fan' ('fann' or 'fanne'). Or spell 'the' as 'ye', though that's really older than the Shakespeare/King James Bible thing, and it's always pronounced as 'the', with no 'y' sound https://en.wikipedia.org/wiki/Thorn_(letter) .
It's not clear-cut, either. If you turn around and the group continues, and they don't die, it's really hard to accept that you made the right choice. Just because they got lucky and survived, sometimes the right choice was still to turn around. But there's no certainty, and it's hard not to second-guess your choices.
