Oh I don’t think he had to talk his wife into this trip at all, as you stated. She obviously stated that “they” discussed this and all whcih would entail the risk...and this not just on this climb.
Same thing goes for car racers and deep sea divers etc..etc...etc...how about hokey players who get whacked all the time....risk.
The bottom line is you cannot set priorities for other peoples decisions....and what they base those decisions on.
Fathers (or mothers, for that matter) of young children should not take frivolous risks. This wasn’t the man’s job. It was his hobby.
