I don't think you can say, "Poor guy" and "all that to survive and is gone" because, in those two years, he actually accomplished a lot. He died in hope, not despair, and died a death most people that die in despair wish they could've died.
The man is a hero, in his own heart and the hearts of all those his charity helps.
I don't think he could've asked for much more than that, to take the death at the road side bomb or live two years to do what he did -- I think that's worthy of all the effort he put into surviving.
I just hope he feels he accomplished as much in his short life that he would've liked to have done.
I wish his family the best, carrying his memory proudly.
