The simple fact that the gentle readers require writers to post extreme wham, and deathfic warnings at the beginning of their stories should give you a good idea as to how such things are accepted.
I'm not the purveyor of death and descruction as much as people may think, but, like Chris, I do regret the loss of dramatic tension that such warnings rob the story of.
That said, I too don't think that a Clark/Superman could actively commit sucide. It's well within his character to give his life to save another. And I think it's possible for him to get depressed enough to take greater risks and more dangerous chances because he doesn't care about himself that much. In that case he could be said to be 'courting' suicide without actually committing the act.
