I haven't read this whole thread yet (although I intend to do so tomorrow) but I really wanted to post, and have changed from my usual username as I don't want to out myself.
I have attended the funeral of a relative who was a road racer, who died at a very young age. I saw his fellow racers carry his coffin, and they were devastated at what happened. These were big names in the sport. Anyway, off the top of my head, every single one of those men is now dead, killed in the same way. I don't think any of them made it much past the age of 30, and some had young children.
But the thing is, it was one of the things they lived for. They knew the risks, but no one ever thinks it will happen to them. Their wives knew this before they married them, they knew this before they had children with them. Without the racing in their life, they wouldn't have been the men that their wives fell in love with. So it goes round in circles......
To say he was unfair on his DC, he didn't set out to race that day and think 'hey, I think I'll get killed?'. No one ever thinks it will happen to them.
You could just as easily apply the same logic to servicemen, saying that they know they could get killed in the line of duty, so they should leave the army before they have children. Because its unfair to their DC too, when they could just take a desk job at home.
I suppose the bottom line is, life isn't fair, so fairness doesn't really come into it. It is however tragic at times.
