I really can't believe that we've made it this far into this debate without this analogy.
In the most popular serial narratives on earth, death of the PCs is a very rare thing and almost always dramatic rather than in a random, non-plot advancing encounter.
I'm referring to TV.
It wasn't raised because said analogy was not apt at all.
In TV, everything is scripted. You don't have main characters dying random deaths because the director mandated that it be so.
But in dnd (or any other pnp game), your fate should be determined by the most fickle of women (ie: lady luck), in the form of dice. You can't say "I am meant to be a hero, so I am not supposed to die to random events like being staked by a frozen icicle of urine dropped out of a passing aeroplane".
Rather, you escaped such a henious fate (perhaps because you made your reflex save or something?). Only then can you say "Ah, I escaped being impaled because of my superior stats, sound tactics and a little luck. I am a hero."
So it is more like a retroactive event where you look back at your accomplishments. The TV analogy is applicable only if you are looking back at your character at lv10 and recounting his feats from 1st lv, rather than as a "live feed" sort of scenario, because that would be the only time you can be certain that you are going to survive to lv10, since you have already experienced it all.
Basically, I just feel that nothing should be confirmed until it has actually happened. I said it before, and I feel compelled to say it again. You shouldn't automatically feel entitled to "benefits" such as "no deaths" just because you are a hero. Rather, you are a hero exactly because you survived it due to your own merit, and not just because the DM made it hard for your party to die. Half the fun of dnd is testing my mettle by pitting my own optimized PCs against the worst the DM has to throw at us! If I die, so be it. It simply means that my character was too weak, so it is time to get back to the drawing board and create a better one.
