*hugs* Ahh, sorry Nonnie. That chapter has made people howl at me a lot!!
Oooh. I think that people will do tremendously brave and powerfully foolhardy things in order to protect those they love – even at the cost of their own life.
I think, given more time and deliberation (and less terrible circumstances), that they both would have elected to live. They didn’t go out there with death being the end-goal in mind. They went out to achieve other goals – Dain to open up a column to Dale and finally kill Dagalur, ending the blood-feud at last, and Bombur to save Bofur. Death was the unfortunate consequence.
No, I don’t think they chose suicide. I think that they’d have wanted to survive their encounters. I think they held onto a tiny hope that they would – Dain, most certainly, knows that it is near-certain, but he still hopes that he might make it.
Bombur isn’t thinking about his stupid leg at all, nor his children or wife or grandchildren – he is FURIOUS and ready to kill every Orc he can see, just to try and get to his brother. An angry Bombur is a very dangerous one!
