The example case of "sanitising" Cinderella, do not have a lot of sense. Sure if you compare the Disney version to the Grimm one, the Disney version look like far less horrific. But the Grimm one is just one of the many versions of Cinderella.

The (probably) oldest know version is the story of Rhodopis, where there is only an eagle who bring the shoe of a woman to the king. Apart from the fact than Rhodopis was probably a slave, there is no need for sanitation in this story.

Also, Disney have used the older Perrault version as a base instead of the Grimm one. In the Perault version, Cinderella forgive her stepsisters in the end. There was no need to sanitise anything.
