Important point many are missing: Folktales were not originally for children. They were told among adults after children had gone to sleep. But when folklorists (like the Grimm brothers) started collecting and publishing folk tales, it became a trend to publish sanitized edition for children.
Read something like the Arabian Nights tales in an uncensored version - these were clearly not intended for children anymore than 50 Shades of Grey are for children. The children's editions are heavily sanitized.
I suspect their change into children literature was because of cultural changes - educated 19th century adults couldn't take folktales serious anymore (except as anthropological studies) and found them childish. The same way that 19th century popular literature like Dumas and Verne became children's books in the 20th century.
Walt Disney is often criticized in this context, but both Snow White and Cinderella are actually pretty faithful to the source material. Cinderella is just based on the Charles Perrault version of the story, not the Grimm version which contain a lot more maiming.
