Disney Villains have a reputation for being killed off in astonishingly brutal ways. But they've got nothing on the fairy tales that inspired them.
Take Snow White's Evil Queen as an example. She tries pushing a boulder down a slope to crush the dwarves who are pursuing her, but she's apparently having such a blast while doing it that she can't help but laugh like a maniac. This gives Zeus the perfect opportunity to intervene. He strikes the cliff she's standing on, sending her falling to her death below...followed by the boulder to smush out what life is left. Now that's pretty dark, but quick and painless compared to her fairy tale counterpart.
In the Brothers Grimm version, the Evil Queen actually attends the Prince's wedding but she doesn't know it's Snow White he's marrying, and the moment she arrives, she's seized by guards who strap red hot iron shoes to her feet. Then, in front of all the wedding guests, she was ordered to dance in said shoes until her body couldn't take the pain anymore and she dropped dead.
