I've watched this conversation with interest, and wasn't planning to step in, as it's exactly the sort of thread that's generally better without me. Author intervention can derail a good discussion.
But after considering, I decided I did want to talk about this topic a little. There are two things going on here. One is the mistake I made with Jasnah in Words, which I've mentioned before. One is a larger discussion, relevant to the cosmere.
Warning, WALL OF TEXT. This is me we're talking about.
You see, Jasnah wasn't originally meant to be a fake-out. Jasnah originally was going to go with Shallan to the Shattered Plains--but she was really messing up the outline, diverting attention from Shallan's character arc and pointing it toward Shallan/Jasnah conflicts instead.
My biggest breakthrough when outlining the book in detail was the realization that the book would work so much better if things I'd planned to do with Jasnah in it were diverted to later books. When that came together, WORDS really started working. Hence her jaunt into Shadesmar. I initially wrote the scenes with it being pretty clear to the reader that she was forced to escape--and it was super suspicious that there was no body.
In drafting, however, early readers didn't like how obvious it was that Jasnah would be coming back. I made a crucial mistake by over-reacting to early feedback. I thought, "Well, I can make that more dramatic!" I employed some tools I've learned quite well, and turned that into a scene where the emotion is higher and the death is more powerful.
HOWEVER, I did this without realizing how it mixed with other plotlines--specifically Szeth's resurrection.
We get into sticky RAFO areas here, but one of the biggest themes of the Cosmere is Rebirth. The very first book (Elantris) starts with a character coming back from the dead. (As I've mentioned before, a big part of the inspiration for Elantris was a zombie story, from the viewpoint of the zombie.) Mistborn begins with Kelsier's rebirth following the Pits, and Warbreaker is about people literally called the Returned. (People who die, then come back as gods.) The Stormlight Archive kicks off with Kaladin's rebirth above the Honor Chasm, and Warbreaker is meant as a little foreshadowing toward the greater arc of the cosmere--that of the Shards of Adonalsium, who are held by ordinary people.
Szeth's rebirth, with his soul incorrectly affixed to his body, is one of the things I've been very excited to explore in The Stormlight Archive--and the mistake with Jasnah was letting her return distract from that.
That said, you're not wrong for disliking this theme--there's no "wrong" when it comes to artistic tastes. And I certainly wish I'd looked at the larger context of what happened when I shifted Jasnah's plot in book two. (Doubling down on "Jasnah is dead" for short term gain was far worse than realizing I should have gone with "Jasnah was forced to jump into Shadesmar, leaving Shallan alone." I consider not seeing that to be the biggest mistake I've made in The Stormlight Archive so far.)
However, the story of the cosmere isn't really about who lives or dies. We established early on that there is an afterlife (or, at least, one of the most powerful beings in the cosmere believes there is--and he tends to be a trustworthy sort.) And multiple books are about people being resurrected. What I'm really interested in is what this does to people. Getting given a second try at life, being reborn as something new. (Or, in some cases, as something worse.) The story of the cosmere is about what you do with the time you have, and the implications of the power of deity being in the hands of ordinary people.
More importantly (at least to me) I've always felt character deaths are actually somewhat narratively limp in stories. Perhaps it's our conditioning from things like Gandalf, Obi-Wan, and even Sherlock Holmes. But readers are always going to keep asking, "are they really dead?" And even if they stay dead, I can always jump back and tell more stories about them. The long cycle of comic books over-using resurrection has, I think, also jaded some of us to the idea of character death--but even without things like that, the reader knows they can always re-read the book. And that fan-fiction of the character living will exist. And that the author could always bring them back at any time. A death should still be a good death, mind you--and an author really shouldn't jerk people around, like I feel I did with Jasnah.
But early on, I realized I'd either have to go one of two directions with the cosmere. Either I had to go with no resurrections ever, stay hard line, and build up death as something really, really important. Or I had to shift the conversation of the books to greater dangers, greater stakes, and (if possible) focus a little more on the journey, not the sudden stop at the end.
I went with the latter. This isn't going to work for everyone. I'm fully aware of, and prepared for, the fact that things like Szeth coming back will ruin the stories for some readers. And I do admit, I've screwed it up in places. Hopefully, that will teach me better so that I can handle the theme delicately, and with strong narrative purpose behind the choices I make. But do warn you, there WILL be other resurrections in my books. (Though there are none planned for the near future. I took some extra care with the next few books, after feeling that things happening in Words and the Mistborn series in the last few years have hit the theme too hard.) This is a thing that I do, and a thing that I will continue to do. I consider it integral to the story I'm telling. Hopefully, in the future, I'll be able to achieve these acts with the weight and narrative complexity they deserve.
If it helps, I have several built-in rules for this. The first is that actual cosmere resurrections (rather than just fake-outs, like I did with Jasnah) can happen only under certain circumstances, and have a pretty big cost to them. Both will become increasingly obvious through the course of the stories. The other rule is more meta. I generally tell myself that I only get one major fake-out, or one actual resurrection, per character. (And I obviously won't use either one for most characters.) This is more to keep myself from leaning on this narrative device too much, which I worry I'll naturally do, considering that I see this as a major theme of the books.

(Sharders, please don't start asking me at signings who has had their "one death" so far. This is me drawing the curtain back a little on the process, I really don't want it to become an official thing that people focus on. Do feel free to talk about the mechanics of resurrection though--it should be pretty obvious now with Elantris, Warbreaker, Szeth, and a certain someone from Mistborn to use as guides.)
