It’s quite interesting that Dr. Bruno Bettelheim (an irreligous jew) who was considered one of the greatest child physchologists of his times wrote an entire book examining childrens fairy tales.
The essence of his work basically made the point (quite convincingly) that each and every one of the famous fairy tales are lessons designed to give over specific points in parable form.
For me it was quite eye opening to realize that what I had always been warned of by my Rabbeiem. That even innocent fairy tales that are supposedly just to “entertain” pose hidden risks as they convey hidden messages that are many times in direct contradiction to our mesorah was in fact documented and proven by an independent outside source who most definetley had no idea what he was writing!
