4. Carnage
(Spider-Man, Marvel Comics)
Some characters are on this list because their deaths were so iconic that they shouldn't have been touched. Some are here because there just isn't a place in the comics for them to exist. But others are here because they sucked really hard, and they should have been dead. Carnage is one of those.
Venom was dark and gritty, and Carnage was an attempt to out-Venom Venom. What resulted was a character marked only by his appeal to edgy 13-year-olds, or those with their general taste profile. His characterization peaked at "crazy", but there was really nothing going on underneath.
He wasn't even scary in the intimate, personal way that Venom was at the beginning. Plus, that brand of over the top villain meshed very poorly with Spider-Man. The only way to make Carnage less interesting would be to feature him in a massive (and massively bad) crossover…Oh, wait.
So, when The Sentry ripped him in half in the opening arc of New Avengers, we all thought we were rid of the guy for good. Unfortunately, we were very wrong.
