A discussion of how and whether judgment regarding the happiness, flourishing or well-being of a life is appropriately influenced by false belief or ignorance on matters central to that life. That is, is it so that what we don't know does not, or cannot hurt us? How much does it matter if the false belief was owing to betrayal or deception by others who mattered deeply to the now dead person? Further, is truthfulness about such betrayal something a friend of a dying person may eschew or is it itself a kind of betrayal?
