Why was Boromir allowed to join the Fellowship?

Oh don't get me wrong, I'm fully pro-Gimli here. It was my intention to actually show that we have to separate Gimli's emotions, such as the previously mentioned terror in the Paths of the Dead, from his natural physical hardihood. So Aragorn already knows that Gimli is not unemotional, but that it's not important because he also knows that as a Dwarf he is enduring - as we later see in their long pursuit of the Uruk-hai, in battle at the Hornburg and elsewhere. As such I think Gimli was a valid choice. I would imagine that the horrors of the Dwimorberg affected him in a way that the more blunt adversity of Mordor might not.
