Here's a post about 10 original fairy tales in their full and gruesome glories. Take, for example, Snow White:
In the tale of snow white that we are all familiar with, the Queen asks a huntsman to kill her and bring her heart back as proof. Instead, the huntsman can’t bring himself to do it and returns with the heart of a boar.
Now, fortunately disney hasn’t done too much damage to this tale, but they did leave out one important original element: in the original tale, the Queen actually asks for Snow White’s liver and lungs – which are to be served for dinner that night!
Also in the original, Snow White wakes up when she is jostled by the prince’s horse as he carries her back to his castle – not from a magical kiss. What the prince wanted to do with a dead girl’s body I will leave to your imagination.
Oh – in the Grimm version, the tale ends with the Queen being forced to dance to death in red hot iron shoes!
