The real problem comes from our board conventions. Any serious wham, or death has little impact, or dramatic value, if it's known a head of time. But in deference to the probable majority of gentle readers who don't want to read deathfic, or unhappy endings, we have adopted a practice of putting warnings on those fics that might contain such subject matter.
Tank, I've always wondered why we do this. After all, don't most people just do what I do? If a fic starts to get a little 'iffy', flip to the last page. If Lois and Clark are together at the end, continue reading. If not, drop it like a hot potato
