> It's what's more important? Doing fan service for fans who will revere your grocery list because it brings them joy? Or leaving behind a body of work you're really proud of and is widely respected?

Since you'll be dead and utterly unaffected either way, I'd go with pleasing the fans. Also, it's really a freebie for your legacy if it's understood that it was written under the influence of dementia and published posthumously.

On the other hand, if I thought it would be depressing or unpleasant to fans more than please them, I would want it destroyed.

But that's what I'd do. Terry Pratchett had every right to make his own decision on this. Even with dementia, that's 100% his call. (Of course, his assistant should make sure he was fairly consistent on this point, when most lucid.)
