The funny thing is the Brothers Grimms actually toned down some of the stories to be better presentable. My favourite has to the be the original Little Red Riding Hood "classification". Basically the wolf asks Red if she wants to go down the "path of needles or path of pins", then while she's distracted by the needles (which is said to represent her maturity, vs the pins which is said to mark immaturity), the wolf rushes to the grandmother's house, kills her, collects her blood in a wine glass/wine bottle, then prepares her flesh (variants include just slicing it, but some cases he makes it into meatballs or sausage), then once Red comes, the wolf tells her to have dinner (which is ofc her grandmother), a cat and a bird try to warn her what the "dinner" is, but the wolf tells her to ignore them, then to take off her clothes, throw them in the fire, and told her to get in bed with him, when he then "lept on her", devoured her and then the story ended. Its very obviously about avoiding suspicious men as you enter young adulthood.
