So, in PoF the Commander dies, temporarily loses memory and personality (which seems to be an event unique to the traumatized souls from the Domain of the Lost), but eventually regains them and continues to function past bodily death. An ally NPC whose name I forget also restores her former self and eventually ends up helping in Kormir's library.
In S4E4, we meet Snaff and Eir and communicate with Glint, who oversees some portion of the Mists and protects those who venture there. Both Snaff and Eir appear to have their personalities, agency, and cognitive abilities completely preserved; from PoF, we know that they aren't just Mist echoes without self-awareness (or at least they don't have to be, as true afterlife existence is proven to be possible).
Thus, the question: why be mad at Logan for indirectly causing Glint's and Snaff's deaths, if they both still exist and can be interacted with? Why is Taimi afraid to die, if she knows she'll just end up hanging out with her perfect mentor and discussing science? Why did Blish decide to transfer his mind into a golem, which apparently made true final death (i.e. nonexistence) possible for him (in the form of taking his higher functions offline), if he could just let his body expire and continue his existence in the Mists? Why do the people of Tyria mourn their dead if they'll just meet them again in the afterlife; death should be an extremely frustrating inconvenience at most, but definitely not something to despair over?
The only possible explanation I'm seeing is that very few ghosts actually get to have a decent afterlife, but that should still produce considerably more hope and less fear.
