I'm not much for deathfic. I prefer happy stories in general.
I will read a deathfic if it's well enough written and if I'm in the right mood.
Oddly enough, though, I actually have written a deathfic. Surprised the heck out of me when I did it, and I don't expect to ever do so again. Still, so far there's one vote from a writer who has written one, and it's mine. Go figure.
