It's important to remember that these stories are orignally an oral tradition that only fairly recently began to be written down. They would have had a myriad of differing versions depending on the preferences of the storyteller, their community and the intended effect on specific audiences.

In a way, retelling these stories in a way that's meaningful to the listeners is the way it always has been. We just have to remember that the darker versions also served a purpose of sense-making, and they can come to serve it again if we need them.

Good on your partner for trying to help those kids.
