What is one of the worst Kick Them While They're Down things a villain can do to show how far past the Moral Event Horizon they've crossed? Easy: After giving The Hero a No-Holds-Barred Beatdown and leaving them a bloody pulp in the dirt, they see the hero desperately reaching out for something in front of them. It could be a Tragic Keepsake, an Orphan's Plot Trinket, or a Memento MacGuffin. Whatever it is, it means a lot to the hero, so what does the villain do? Right when it's in reach of their fingers, he smashes it to bits under his foot. For extra cruelty, he might stomp on it multiple times or just grind it under his boot before scraping the fragments off the bottom.
Apart from being cruel, a villain sometimes does this to demoralize the hero, as it has sort of a symbolic theme behind it: the destruction of their precious Plot Coupon representing that the hero has failed and hit rock bottom; the one thing that kept him going is gone, so there's no hope left, thus making it a literal Hope Crusher. Other times, however, the villain just made a big mistake and causes the hero to go into an Unstoppable Rage.
If the villain does it incidentally while doing a Power Walk, it's Trampled Underfoot. See also Wrecked Weapon, Weapon Stomp, Agitated Item Stomping, Symbolically Broken Object. Related to Smash the Symbol and It's All Junk. Subtrope of Kick the Dog.
WARNING: Since this trope is often invoked before or during the climax, expect spoilers below!
- Rinne Berlinetta from ViVid Strike! had her tiepin destroyed when three bullies beat her unconscious. Oh, and all of this was going on while her grandfather (the one that made the tiepin) was dying. Needless to say, she made them suffer the following day.
- In Yu-Gi-Oh!, two different bad guys destroyed precious cards from Yugi to prevent him from using it and also just for the sake of being awful persons. The first is Kaiba who ripped Yugi's grandfather's Blue Eyed White Dragon so he would be the only one to have copies of this powerful rare card. So second is Insector Haga/Weevil Underwood who threw overboard the even more rare and powerful Exodia the Forbidden One cards before the beginning of a tournament.
- Inverted in JoJo's Bizarre Adventure: Battle Tendency, where Joseph incinerates the headband he gained from Caesar's Heroic Sacrifice as part of his ploy to defeat Wamuu. Because Wamuu was the one who killed Caesar, Joseph decided that destroying Caesar's keepsake this way would only honor his memory, as it would allow him to avenge his own death.
- In Yuri Kuma Arashi, the Invisible Storm does this to Kureha by burning down the flowerbed (which was very precious to her as it had sentimental links to both her dead mother and her late girlfriend Sumika) on her birthday. And then they would have burned Sumika's last letter to her in there as well, forcing her to watch no less; had Ginko not jumped into the flames to save it at the last second.
- In Zero Hour!, Parallax discovers and retrieves the original Green Lantern ring used by Alan Scott after Kyle Rayner accidentally loses it (Alan Scott had opted to retire after the Justice Society was decimated), then destroys it by smashing it under his foot as he goes to set off another entropy wall.
- When the Masters of Evil invaded Avengers' Mansion, Mister Hyde destroyed the few mementos Captain America had from his life in the 1940s in front of him. These included his original non-indestructible shield and the only photograph Cap had of his mother.

- At the climax of Atlantis: The Lost Empire, Rourke, after obtaining the Atlantean crystal and having no more need of him, punches Milo in the face. Milo's framed picture of him as a boy with his grandfather falls out and Rourke stomps on it, smashing the frame. Fortunately, the photo is intact, and what's more, it's this act that causes Audrey, followed by everybody else except Helga, to do a HeelFace Turn and abandon Rourke.
- In The Great Mouse Detective, Ratigan takes the wind-up ballerina Mr. Flaversham gave her daughter Olivia and crushes it in his hand, both to show Flaversham what will happen to her if he doesn't comply and to give a glimpse of his inner beast.
- Cinderella's stepsisters cruelly rip apart her first ball gown, which had belonged to her late mother (her animal friends had also just spent the whole day altering it for her, to add salt in the wound). It prompts a Heroic BSoD, until her Fairy Godmother turns up to help. In the live-action remake, in addition to the dress-ripping, Lady Tremaine also smashes Cinderella's glass slipper, which was her only memento of the ball (and the happiest she'd been in years), though it also served the more practical purpose of destroying the proof that Cinderella is the girl the prince is looking for.
- Barbie as Rapunzel: Near the film's climax, Gothel destroys Rapunzel's magic paintbrush to keep her from using it to escape (paintings created by the brush can turn into portals to real-world locations), though it was also a gift from her long-lost parents on her first birthday, whom Gothel falsely claimed had abandoned her.

- The villains of John Wick actually kill the titular character's beagle puppy, who was a gift from his late wife to help him grieve after she died of a terminal illness, simply because she wouldn't stop barking in fear whilst they were beating the crap out of John to steal his car keys. As it turns out, this was a really, really bad idea, because John is an infamously badass hitman who subsequently decides to come out of retirement to hunt down the men responsible.
- Downplayed in Memoirs of a Geisha. A jealous Hatsumomo attempts to burn Sayuri's handkerchief, which was given to her many years ago by The Chairman, whom she harbors a forbidden love for.

Ys took said stone and crushed it, fusing Annie's self and her etheric self back together in the process.
