I remember when I looked through the trade paperback as a youngster. It really was a sad comic book.
Unfortunately, if you kill off a superhero today, it means next to nothing for two reasons. First, the idea's been done to death (the most appropriate pun if you ask me). Second, the very concept of "superhero" has been diminished. These days, it'd be a relief if a lot of superheroes died - they'd no longer be miserable, or they'd no longer be assholes.
