This happens to Guts in supremely heinous fashion during the end of the Eclipse when he is forced to watch his lover Casca be brutally raped to the point of insanity by his best friend turned Big Bad Griffith, who has become a demon god named Femto. He tries to reach her by chiseling off his own arm which was trapped in the jaws of a demon, only to be dogpiled by more demons before he can and is forced to watch the rape as a demon claws out his right eye. It's made even more heinous in that Casca was forced to look at Guts in the middle of her rape by Femto when he began to rape her from behind. Not only is Casca being degraded more and worse by the minute, but she has to look at Guts while it happens, and it's heartbreaking to see Casca beg Guts not to look at her during her last sane moments, even though he's just as forced to look on while he's still trying to get to her.
Earlier (but later chronologically), in volume two of the manga, Vargas, the kind but deformed and revenge-driven fugitive, recounts how he was forced to watch as the Count ate his wife and children. This alluded to Guts's own experience with Griffith.
And Guts forced Theresia, the Count's twelve-year-old daughter, to watch as he stabbed the mutilated but still living Count dozens of times. He actually dragged the Count over to her so she'd have a front row seat. This was one of Guts' darker moments.
In Rideback, though it only gets to implying such before he gives in, the main character's brother is forced to give false confession by threatening to rape his sister in front of him.
In Naruto Itachi has twice used his Mind Rape abilities to make Sasuke watch as Itachi murders their entire family over and over and over again.
Seras Victoria from Hellsing has a rather dark and disturbing backstory, which seems to have happened when she was very young. It consists of her father being murdered by burglars, her mother hiding her in a cupboard to protect her, and her mother's subsequent murder by the same burglars. Seras tries to exact revenge by stabbing one of the guys in the eye with a fork; she gets shot for her trouble and one of the perpetrators proceeds to rape her mother's corpse, due to it being "still warm". In full view of little Seras, who lies on the ground bleeding profusely.
Nnoitra orders his subordinate Tesla to beat Ichigo to death and grabs Orihime (who's in love with Ichigo) and forces her to watch. He even says "I want you to watch while the guy who came to save you gets torn apart." Thankfully, Kenpachi pulls a Big Damn Heroes moment before Tesla can kill Ichigo.
Similarly, when Ishida and Orihime arrive to the place where Ichigo is fighting Ulquiorra, the latter lampshades the trope when he tells her (paraphrased) to "watch as the person you love the most dies", and then blows a massive hole in Ichigo's chest, killing him.
In Tantei Gakuen Q, while she and Ryu investigate a girl's vanishment in a Boarding School, Megumi is caught and kidnapped by a mysterious masked man. She finds herself Bound and Gagged and is forced to watch as said masked man kills the also kidnapped Student Council President by smashing a bottle in his head.

He has not, and Megu is released unharmed but very shaken by what she was forced to see.
In Digimon Tamers, the D-Reaper forces Sakuyamon and Gallantmon to watch Beelzemon fall to his death by sending a Zerg Rush of its Agents at the former and physically restraining the latter.

Averted in Rurouni Kenshin. Because Enishi did not force Kenshin to watch as he "killed" his love interest Kaoru even though he knew what affect it would have on Kenshin, this set off Aoshi's suspicion that Kaoru was not dead at all.
In the climax of the 'Saint Beasts' arc in YuYu Hakusho Suzaku has a giant screen showing the footage of Botan and Keiko being hunted down by his bug-kzombies. At first this serves mostly as a distraction, but as Yusuke increasingly gets the worse end of the fight and things get tighter and tighter for Keiko, it gets closer to torture, culminating in Yusuke on the ground, beaten past moving, while the zombies close in on Keiko. (Botan is not in real danger, as her real form is a spirit the zombies can't touch.)
Happens in Deadman Wonderland to Ganta when he is strapped down and made to watch Senji lose an eye during a penalty game. There was no point to this; Tamaki was just being a dick.
In Haou Airen, this happens thrice. In two of these times, the person forced to watch is the same:
Fiest, Kaafai is forced to witness how Hakuron rapes his girlfriend Kurumi, whom Kaafai himself has just befriended. This turns out to be VERY plot-important: it inspires the mentallybroken Kaafai to join the police, learn how to handle guns... and to shoot Hakuron dead the next time their paths cross.
Also used when a rival Triad gang kidnaps Kurumi, and their leader has Hakuron watch via video as he strips and molests her.
In Shaman King, Faust VIII has Yoh forcibly restrained by skeletons and forces Yoh to watch him torture Manta.
Happens more than once in Detective Conan, being a mystery series and all. In example, Conan and his friends are given a tablet supposedly coming from Officer Takagi - and when Takagi's girlfriend Sato turns it on, they see it's connected to a camera that shows them a kidnapped Takagi inside a Death Trap. So they either they find and free him soon, or they'll only be able to watch as he dies — either by hanging in a makeshift gallow, by being blown up by a time bomb, or simply by freezing to death. (He's rescued in the nick of time, though.)
Black Mask is fond of this technique as a torture tool; he drove Catwoman's sister insane by torturing her husband to death and forcing her to watch and eat the bits he cut off.

The Young Avengers/Runaways Civil War crossover has one: The Warden kidnaps Billy, Teddy, and Karolina (bringing Xavin's dead body along), and preceeds to perform a vivisection on Teddy, while his boyfriend is forced to watch, able to hear everything except his own voice. This leaves said boyfriend brokenly trying to use his powers to kill The Warden.
Typically a key part of the creation of a new revenant in any given episode in The Crow series. It's especially bad when fans of the first movie read the first comic, and realize just how loose an adaptation it was.
Done to the audience in Alan Moore opus From Hell. An entire issue is spent on the grisly details of one of the killings and subsequent mutilations.
In one New Gods/Superman story, Darkseid forced Mr. Miracle to watch a porno that his wife and Superman did (while brainwashed by Darkseid's rejected underling, Sleez).

In the Fallout: Equestria universe, memory orbs - magical devices which allow unicorns to experience the collected memory within - cannot be exited until the memory has been played completely. No matter how horrific - or embarrassing - the memory is, once you've activated the orb, you're forced to watch (and feel, and smell, and taste) it all.
In The Chong Sheng Trilogy's third installment, Chiang pulls this by torturing Katara with acupuncture and forcing Zuko to watch. Initially it's to make her tell him about the White Lotus' plans since she just succeeded Pakku as the Grand Master of Water, but evolves into the Kick the Dog variety once it's clear she no longer has the capacity to divulge any information. Bonus points in that Chiang makes it clear what he intends to do to her once she passes out. He doesn't succeed, as Hakoda and others still loyal to Zuko pull aBigDamnHeroes moment out of the proverbial fire.
One Fullmetal Alchemist fanfic involves Envy employing this method on Edward, as he and Sloth engage in some kinky and graphic 'bonding', which proves to be a fairly effective way of squicking out poor Ed especially since this fic is set in the first anime continuity, where Sloth is actually a resurrected version of Ed's mom Trisha. And to add insult to injury, Envy transforms into his and Ed's father, Hohenheim!
You Obey by Kalash93 contains a very interesting and somewhat meta spin on this trope.

In "What if Snape Died", Voldemort didn't know the prophecy but that just delayed (for a few years) the moment Harry Potter would become the Boy-Who-Lived. Some of his Death Eaters forced James to watch as he tried to kill Harry. Since Lily did sacrifice herself after all, the Killing Curse came back at him like in the book series.
Subverted in Red vs Blue: Revenge of the Robots. Unless Sarge gives O'malley what he wants, he'll be forced to watch Wyoming not kill Grif. Which considering how much Sarge hates Grif, is an unbearable torture.
A horrifying version happens in the Lost Girl fic Faeral. Dyson has, for complicated but well explained reasons, gone psychotic and previously tried to rape Lauren. When Bo is talking to him later, he is confused as to why she is angry over it. He then concludes that as a Succubus, she wants to watch him rape Lauren. Bo damn near kills him on the spot.

It destroys his entire view that the Alliance is truly making the universe a better place, which is the reason he was doing horrible things for them.

Invoked in The Green Hornet. "He took my favorite toy, and he ripped the head off. Right in front of me."
Bryan Mills threatens to invoke this in Taken when confronting a corrupt French agent about the whereabouts of his kidnapped daughter. After the agent attempts to intimidate him into dropping the case, Bryan shoots the agent's wife in the arm, assures him that he only winged her, and orders him to help, or "the last thing you'll see before I make your children orphans is the bullet I put between her eyes."

In Underworld Rise Of The Lycans, after Sonja is tried and found guilty of high treason mainly due to her being impregnated by her lover, the werewolf Lucian, with a child who would be half vampire, half werewolf, her punishment consisted of having her chained to a pillar and Lucian chained to the floor face-to-face, where she was forced to watch Lucian get whipped. Then, it all gets worse when Lucian was then forced to watch her get burned to death by exposure to the sun.
A rather chilling example in Strange Days: a rapist blindfolds his victim, then hooks her up to the memory-recording device he's using at that moment... forcing her to experience her own rape and subsequent murder as though she were in his body. So not only is it happening to her, she's forced to get off on it the way he is.
In The Avengers, Loki threatens to have Clint, who's under Loki's control, ambiguously rape, torture, and finally kill Natasha, and then release him from the mind control to allow him to see what he did before killing him. A bit of variation, however, as it's Natasha who he is threatening.
Red Eye: Inverted. When Rippner faces Lisa in their final confrontation, Rippner tells Lisa that he is going to make her father watch what he's going to do to her (instead of the hero/heroine watching a loved one get harmed). Whatever he was planning on doing, it is averted in the end.

In The Saga of Darren Shan, also known as the Cirque Du Freak series, the second-to-last book gives us this between Steve and Darren. "I dare you to do this." Different in that Steve is essentially doing it For the Evulz at this point, and if Darren also does it, it'd keep Steve from actually realizing and becoming truly evil, and if Darren doesn't, Stevewould go absolutely batshit crazy. Ultimately it's Steve killing Darren's godson and son-of-best-friend Shancus, that is Steve's crossing the Moral Event Horizon and he dares Darren to do it as well.

In the New Series, the Master also does this to the Doctor, forcing him to watch Earth literally get decimated while helpless to stop him. Why? For the Evulz, of course! Most villains find that this is the most effective way to break the Doctor. In Season 1, the Doctor was forced to reveal who he really was when Rose was getting tortured in front of him.

The Space Cases first season finale contained a textbook exmaple, where Warlord Shank demands information about the Crysta from Harlan after some of the gang have been captured and tied up. When Shank brings out his Agony Beam, Harlan, of course, defiantly tells him that torture won't make him talk. Shank calmly asks, "Who said anything about torturing you?" before turning it in the direction of the unconscious Catalina. Good thing he also didn't say anything about giving him truthful information.

In this alternate future, the terrorized islanders would have risen up against Makuta's rule, only to be brutally killed one by one by his henchmen. This also counts as Mind Rape, as it leaves the victim too shaken to try to escape Karzahni's realm.
Knights of the Old Republic: Admiral Saul Karath eventually manages to capture the heroes and starts grilling the Player Character for information.

In an American Dad! episode Roger goes on a campaign to ruin the life of a man named Sidney who Roger believes stole from him. This vendetta includes destroying Sidney's garden and raping his favorite sycamore tree. Later, Roger sends Sidney a letter that says, "Your sycamore had saplings. I made them watch."
In an episode where Stan puts his mind in the body of a horse, he (in the horse body) keeps getting poked in the face by a little kid despite Roger warning him not to. To the kid's shock, horse-Stan threatens to go to the child's house and kick his mother to death while he watched.
Freakazoid! had a mild version of this played for laughs. The villain, Gutierrez, wants a code that will give him super powers. When the hero and his mentor refuse to give it to him (the hero doesn't even know the code), he reveals he has the hero's family captured as well. The method of torture used on the family? The best of Marty Ingles.
"What kind of sadistic creature are you!?!"
In the Spongebob Squarepants episode Krab Borg, SpongeBob and Squidward think Mr. Krabs is a robot who can talk to electronics. They tie him up and force him to watch them interrogate his expensive appliances. Most of them end up destroyed, making the money-grubbing crab scream and cry.
All in vain, as Spongebob realized the whole thing was all in his i.ma..gi...na....tionn — oh look, there's Halley's Comet! (runs away).
The Clock Orange scene mentioned above is parodied when Mr. Burn uses a similar device to force Santa's Little Helper to watch scenes of terrible violence in an attempt to make him a vicious attack dog.
One episode of Avatar: The Last Airbender has an Earth Kingdom general try to force Aang into the Avatar State by making him watch as he slowly bends Katara underground, presumably to suffocate. It works.
In the Rocko's Modern Life episode "To Heck and Back," Heffer is confronted with his gluttony in Heck, and forced to watch Rocko dying inside his guts (after Rocko fell in while trying to retrieve a chicken bone that had gotten caught in Heffer's throat.)
In the final episode of Justice League Unlimited, Darkseid tells Superman that this is his plan. He talks about how he is going to destroy the planet and kill everyone on it, and only after Superman has seen it, will he kill him.
A Family Guy episode has Peter doing the really old cartoon gag where the steam coming off a freshly baked pie forms beckoning fingers and tries to go up Peter's nose, which is supposed to draw Peter into eating the pie. When Peter refuses, the steam somehow starts ripping off Peter's clothes so it can rape him. We then see the steam is also holding Quagmire's eyes open, forcing him to watch.
In Buzz Lightyear of Star Command: Zurg manages to capture Booster, XR, and Mira and gloats about the tortures they are in store for. He's especially proud of Mira's, saying she can ghost right out of cell. Doing so however causes alarms to go, breaking her concentration, leaving her in her cell. The torture is that she has to watch her teammates be tortured, powerless to stop it. Except it's a kid's show. So XR finds being stretched enjoyable (it gets out the kinks); and while Booster's cell is supposed to turn his strength against him and throw him around the room, he sees it as a Bounce House and great fun. So Mira just smirks at him.
Syndrome does a variation of this to Mr. Incredible in The Incredibles; he's made to listen to a radio transmission from his wife and children as their plane is being targeted by bombs.
