I think that every culture has to some degree the inclinement to edit older stories, to make them more apropiate for that culture.
Christianity edited innumerous pagan stories to get the element in that God was after all the supreme being, and many old heroes and gods were pushed in minor roles, got a more chaotic or evil role, etc.
Consider for example the Christmas tree, the Nordic pantheon, etc
Other stories were edited to get them more social-political correct.
For example SnowWhite and the "true love kiss".
Just imagine.... you, a male, see a beautiful young woman sleeping, all alone in the forest.... what do you do ?
In todays romantic version you fall in love and give her a "true love kiss" and the happy end is there.
In the older European version the girl was taken before she really knew what happened, raped so to say, and after some hence and forth, the male did the "honorable" thing: he married her.
I wonder whether this version was not also already edited, and what the more original version was.
Another example (I love fairy tales since I was a kid

)
Cinderella
The poor girl, doing dirty work, ash of the fire on her clothes....... and because of that tiny shoe, that she could wear, and not her stepsisters, got the first price of the lottery of life: get married with a rich guy. The romantic era happy end.
The older story is about a Shamanka (a female Shaman), guarding the fire, who gets access to the spiritual world, and her "stepsisters", who are focused on earthly material things, lose forever the possibility to get there. The happy end that Cinderella is able to travel between the worlds (without using drugs !.... as proven because she fits the tiny shoe without getting bleeding feet like her sisters)
Cinderella, also Assepoester, Asschenputtel, Askungen, Cendrillon, Ye Xian, as someone who learned to be a true Shamanka, is a story that is in various versions present from China to Scotland.
All really intersting stories, if you like the relation between culture and fairy tales.
And BTW considering the more original version, the Cinderella story could easily be many thousands of years old, perhaps as old as the first Shamankas in history.
I guess that living in a world where culture is changing all the time, we have to deal with that editing.
