The guiding company says "... the Sherpas urged Ms. Shah-Klorfine to turn around and abandon her bid to reach the summit, but she refused to stop."
So whose fault is it? If the husband believed she was too inexperienced to climb Everest, as he states, and he couldn't talk her out of it, why does he think the guides should've been able to talk her out of it?
So is climbing Everest become more dangerous because of guided trips? No.
"In the end, 10 people perished this spring on Everest, making it one of the deadliest years on the mountain. But around 550 people made it to summit, among the most ever. Ultimately, guiding has reduced the chances of death, said American mountaineer Mark Jenkins, who reached the summit in May.
