Steve and I actually had a talk about that. About the initial reaction of "it just isn't FAIR" that I had. And then the realization that, no ... it is neither fair nor unfair. As much as this hurts us, his death is no more fair or unfair than any other person's death in the universe - the people who cared for that other person are just as sad. And the fact that we (as in "us humans") react like that stems from the fact that we hope everyone dear to us gets to live at least as long as their statistically calculated average lifetime and does NOT have to go earlier.
But in the end, it is and always will be, very random and we just have to accept it and go on.
I just really don't want to accept it, this time. (It also has been the fourth death of a person close to us, this year, and we are just DONE ... not to mention, incredibly sad.)
