I know the inmate death of a hero will get customers to buy comics for a while because of shock value or maybe the mentality that a book might be worth something. Isn't the result however only short term? The long term result would be that once a hero is dead there are no more stories unless the character is brought back in someway or the occasional flashback. It is for this reason that I believe we see so many stories of heroes dying and coming back. They have to come back in order to sell more books. As I said dead heroes don't sell comics unless your Deadman and now he is not even alive (That is unless something just happened).
I get really annoyed with the deaths in comics not because they have them but because they are so prevalent. You need to have an occasional death to have suspense in stories. To me it seems however that there is an overwhelming number of deaths in the past ten to twenty years. I think it all started with Superman everyone went nuts about his death and then it seem there was a steady inclination in the body count. When Batman died a while ago no one believed it would be permanent. What was the saying the only hero that stays dead is Bucky, and then he came back.
Not just heroes but just people in these universes are slaughtered. It is seeming that all the superheroes are failures. They only seem to stop a villain after they have a large body-count. I like the idea of a hero actually saving lives and preventing death. The argument for these deaths I hear is that it somehow it is more realistic. I would argue that it is less realistic. For starters were dealing in a world with superpowers and magic but with things like time travel, cloning, alternate universes, magic, and gods every reader knows that death is not permanent. How realistic is that.
I could go on forever but let me say one more thing. I am sick of reading about dark brooding heroes. It is becoming that all heroes suffer from horrible tragedies. It works for Batman but for every Batman there needs to be someone who is actually happy. Maybe even enjoying life.
