Anything outdoor can be dangerous, he could as easily died fishing with his children, just because mount Everest is more dangerous you call him an idiot. I’m sure that his family is sitting around calling him an idiot.
As easily? Fishing does not kill or maim 10% of everyone who tries it. Climbing mount Everest does. The man was a damn fool. I feel sorry that his children had a selfish egotistical idiot for a father. Now they don't have even that.
And if you think fathers can just as easily die taking their children fishing as climbing mount Everest, then you are TSFW.
