Do dead Superheroes sell comics?

 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.

"I believe the saying is "Nobody stays dead except for Bucky, Jason Todd and Uncle Ben"...and Uncle Ben is still dead so there's hope for us all! "

Dead heroes aren't interesting, but I find the aftermath to be. Such as Bucky becoming Captain America, Dick becoming Batman, etc.
 
Dead heroes do sell comics. The issue where they actually died usually gets multiple prints. The aftermath sometimes does, sometimes doesn't. 
 
To clarify:

" Writers need to weigh the pros and cons before they go slaughtering random characters. "

I buy Captain Marvel comics all the time, and he's been dead for a while.

 
I would say a death will sell a comic quicker than no death.

I believe the lack of deaths throughout the 60s-85 got people questioning the mortality of their favorite characters

Being dead is Deadmans' whole thing. He's always been dead really, except before he died, if you know what I mean. Have I misunderstood what you meant?

He came back to life last month, and was then killed again. I imagine he'll be back to his old self soon enough.

I would say that they shouldn't kill anyone unless they're will to let them stay dead, but this is comics and that's not happening, so I say don't kill anyone they're not willing to let lie for at least a year.

@V_Scarlotte_Rose: Yes I was making a little joke about Deadman. I thought it was funny. =)

You are right but now the door has swung the other way. No character stays dead so we still have the question of mortality. I know that Ted Kord is dead now but he will come back. They all do. Vibe for example will be back in his own series in a few weeks. It is serial mortality. Death means nothing in comics. I've gotten so jaded to comic deaths that it doesn't bother me that they died. I am only annoyed that I have to wait years for them to come back.
