So? Are you seriously suggesting that if the family had disapproved of his mountain climbing, they would actually say so in a public interview?
'We're terribly upset and saddened and she'll never know her father, but while we're suffering in public, we'd like to mention that we were against the whole climbing thing in the first place. We told you so, John!'
Someone doesn't have to be a complete narcissist to occasionally behave in a narcissistic manner. Hell, we all act narcissistically from time to time (some would even say all the time).
