Sounds like you started out with a sound mind and good decision making, even as an amateur. I believe in most cases of tragedy, the wrong decision at a key time can send someone down the rabbit hole and they can't recover from one bad choice. The few times I have had a crisis in the mountains, the first thing I did was to stop, sit down and take a breather. Get a drink, eat something, then attack the problem with calm logic. Getting below treeline is an important step in bad weather up high and people make the mistake of doing that without a trail and that is a critical mistake. Panic completely impairs your logical mind. I got caught out in bad weather with someone last year and the first thing they said was, "we need to turn around". I thought about it for a minute and to me, continuing the loop and descending a longer but easier route in bad weather made more sense. The footing was better, the route had no cliffy sections like we climbed up and we would have complete cover from a deep forest from the storm. She reluctantly agreed, more because I was not turning around and no way she was leaving on her own. She ultimately agreed we went the right way later when the sun came out and we had a beautiful walk down. I am primarily a soloist, I like being a dictator out there and doing what I want without being diplomatic, it has served me well for 40+ years of classic routes.
