I agree. Help the other climber. Period.
I also believe, however, that these people are dumb***** for attempting the climb in the first place...and for those who will leave behind families, shame on them for the needless and worthless risk. If they want risk, join the military (if American or British) and put their sense of adventure to productive use.
I think this story strikes a nerve with me because I recently chatted with someone on FR about why I don't watch sports anymore, one reason being the commentators who are all trying to be Olberman, the players who are more into "bling" than sportsmanship.
The casual tossing-aside of human life in this story seems part of a greater theme.
