Robin Hanson expressed some doubts about this list back in 2010: https://www.overcomingbias.com/2010/11/deathbed-regret-is-fa...
> Ms. Ware said regrets are expressed “when questioned about any regrets they had or anything they would do differently”; my wife isn’t thrilled about this as a care technique.
Or:
> Deathbed folks are usually far from their analytical peak – they are often in great pain, and rather muddle-headed. So why would we think their comments especially insightful?
It also gets comically reductionistic:
> Added 9a: Stephen Smith suggests these regrets are the predictable result of opiate pain medication.
But I think it's more about the author trying to force his opinion, when it's not really needed, insightful, or that useful.

(And, beyond asking: is she the type people would trust with such things, or e.g. does she come of as more cold, etc? There can be many factors).
