As an avid fan of comic books, death in fiction has less of an impact on me. After all, everyone knows that he's only dead until someone goes back in time or clones him or brings him back with some spell or his alternate reality self shows up. Death is only permanent for unlucky girlfriends, because the hero has to learn important lessons like "you can't cheat death."
As for anime, Sunrise taught me that you're not dead until you see the body, and Gundam taught me that he still probably isn't dead, he's just evil and wearing a mask now. Higurashi taught me that I'll just have to try again and maybe I won't die this time around. Because seriously,
people don't die, even if they are killed. Oh yeah, and anime in general has taught me that all good heroes have at least one dead parent (two or three is optimal). But I suppose Disney already taught me that one.
Real life situations are an entirely different matter, but in fiction, deaths don't do too much for me. I will say that certain deaths in SOME stories have impacted me quite a bit. But those stories tend to be grounded pretty solidly in reality. No crazy yandere chicks with giant knives, no exploding space ships, and no evil demons.
