Somebody who lives a good life in the wilderness and who never learned about the gods from a priest or something like that is doomed to eternal suffering without even knowing why"
This is the opinion of a companion in MotB. She is a half celestrial who used to work for Kelemvor, but she did not like how things are and now she is a cleric of Ilmater who wants to destroy the wall to end the suffering of the souls in the wall (current ones and future ones).

Some other companions actively reject the gods because they hate the current system. They join the fight because they don´t want to end in the wall.

These are the opinions of companions in a (very good) computer game. I do not know the official lore.

Videogames are unfortunately the last tier of canon, almost everything else will supersede the canon events of a videogame if there is a conflict in story or lore.

However, as far as I am aware, there is no conflict in canon, and Kelemvor himself disliked the wall (because the way Myrkul set it up, it was deliberately punishing people who were just ignorant or isolated. Myrkul was all about promoting worship through fear), which was also mentioned in a novel, so it is canonical.

As for the actual status of the wall, it's in debate. Kelemvor could not take down the wall, but he could change it, which I believe he did in a novel, but I haven't read it. As of 5e, we have at least one sourcebook that talks about people going to the upper plains that best suit them, rather than the wall, but it was still mentioned as being a thing. BUT, the wall was actually errata-ed out of that sourcebook, so people have been questioning whether or not it still exists. Maybe we'll get an answer in the planescape release next year, I hope so.
