I’m also interested in an answer to this question. I read the exchange here, and I found lsusr’s response very reasonable in isolation, but not really an answer to the main question: if past-you didn’t think he was suffering, and present-you disagrees, why should we take the side of present-you? To me, it’s natural to trust hindsight in some domains, but when it comes to the question of what you were directly experiencing at a specific time, the most natural explanation of your changed opinion is that you either have adopted a new definition of ‘suffering’ or are recalling your memories through a new lens which is distorting your view of what you were actually experiencing in the moment. (I think the latter is quite common, e.g. when we nostalgically look back on a time that now represents hope and excitement, but actually consisted largely of frustration and anxiety.)
