Even previously, being "Faithless" was not a simple or accidental thing, KR - it was deliberate and active. Your average farmer who was mostly practical but gave offerings at festival times to different deities related to what they needed and didn't specifically worship anyone was Not in any danger of being marked faithless. To be Faithless, such that you risked the wall, was a much bigger thing than simply not actively worshipping. It was to actively renounce the gods, or to worship them falsely, paying empty lip-service. Anyone else would generally be picked up by whichever deity felt most responsible for them (farmers who worked the land and gave an offering to Chauntaea at planting time would usually be collected by her if they swore to no particular other deity, for example) or, if unclaimed by any specific deity, were judged by Kelemvor directly, who determined their nature and either sent them to whichever domain most aligned with their nature and practice in life, or meted out a suitable other fate, if he deemed such appropriate.
