No. There's an implicit disbelief in storytelling about the hero's mortality -- he's not supposed to die, he's not going to die, and if he does die there's a trick to it, or there's justice coming, etc. That's part of what shocks/frustrates people about the ASoIaF series -- Martin doesn't abide by the rule that characters can't die until their story arc is complete, and it's very difficult for readers to handle it. 

Which brings me to the point that you typically can't 'cheapen' death in fiction, because death in fiction is already inherently cheap. Heroes don't die unless it's in slow motion; nobody's gone until they get their last words; they're not in any danger until their Chekov Gun is out of bullets. Resurrections aren't any worse than any of the usual bullshitty death tropes. You can certainly do it in such a way that it detracts from the story (Thor movie comes to mind, but that whole thing was an abortion), but it's not automatic.
