Sorry previous posters but I have to disagree. IMO it's more of a psychological aspect Kishi is showing us through the "various" flashback differences that, "When searching for the truth of a situation, all perspectives (no matter how different) are equally valid."
In other words the truth of a person or events of nature as recalled by the people who experience it, are all going to embelish their points of view (as well as personailites and moral operandoms.) thus creating many different versions of the same story.... We as the readers must discern the truth from the collective.....(especially if you take to heart the dialogue between Hashi and Madara in the lastest issue about yin and yang (opposing forces co-operating = peaceful stability)). I say take to heart as the two primary players are Hashi and Madara, with everyone else offering their encounters and recollection of the transpiring events that led up to those individual's need to explain their knowledge of the fore-mention two primary players.
This is also why I am under the impression that after Hashi finishes his flashback, we will get Madara's side (thus fluffing the series for a few more months and prolonging the ending).....Even though I feel we already know Madara's side from Tobi's rendition of the tales of Madara.....
If that doesn't happen after Hashi finsihes his flashback (answering Sasuke's question) then I will be assured in my understanding that the truth Kishi wants us to discern is the truth of Madara's character (as it seems to be the focus of the flashbacks pertaining to him and the purity of his evilness (( as is the same for the developement of our main antagonist Sasuke ...is he good ,will he be bad and if so how bad ((( and as for all the other flashbacks have been used to inform about another individual or the developement of infrastructure for the narutoverse))).
So, while I disagree with the other posters, practicing my own advise I speculate that Kishi may be doing it all as we sse "it" or we are people who use our passion to invest a little to much in to something that doesnt exist......if I may relate to the thread starter and their reference to love being lethal, "We want the people who inspire and enetertain us to be more sophisticated then ourselves, but under scrutiny we realize that we are all human,,,, and therefore imperfect"......So maybe Kishi is not trying to teach us something about truth, or waisting our time by prolonging a story that should have ended by now, or that we are all individuals that have to much free time, or that it is a plot hole because the wirter has a lack of continuity or skills in making and executing outlines and story longivity....
