This happens to Guts in a 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 is the person whom Ichigo has come to rescue) 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. Few later, Ryu and other kids find a video featuring this as well as how the masked man threateningly approaches poor Megu and the scene goes to black, implying he's killed her too. 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. Gallantmon can't break free, and by the time Sakuyamon is done with the Agents Beelzemon's too far away for her to help. Fortunately, he's not too far away for Grani to help.
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.. He was right.
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.)
In Haou Airen, this happens thrice. In two of these times, the person forced to watch is the same:
First, 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 him to watch as he vivisects 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 who's Bound and Gagged 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.)
In Saint Seiya, it takes place once in a while. The biggest example is Cancer Deathmask using his Psychic Powers not only to restrain a girl named Shunrei and lift her up several meters over a waterfall located at the other side of the world... but to force her prospect boyfriend/adoptive brother Shiryu to watch as he tosses her into the waterfall and to her death. Though this massivelybackfires, via pressing Shiryu's biggest Berserk Button to the core and sending him intoa huge and gloriousUnstoppable Rage. (And it turns out Shunrei survived thanks to Old Master Dohko's efforts.)
Played with in Hell Girl. A little girl named Tsugumi Shibata is somehow able to see through Ai Enma's eyes as the Hell Girl meets with her clients, and she uses this ability to help her Intrepid Reporter father Hajime track the clients down and attempt to tell them not to take Ai's deals. As an adult, she still has this skill.
In The Disappearance of Haruhi Suzumiya (the movie followup of The Melancholyof Haruhi Suzumiya), Alt!Yuki is forced to watch when [[Yandere Ryoko Asakura stabs Kyon. Ryoko even spins around, waves the knife, and splatters blood on Yuki's face!
Dragon Ball Z: In order to hit Gohan's Berserk Button and see his true power firsthand, Cell spawns seven Cell Jr.'s and then sics them on the other Z Fighters while Gohan watches helplessly, and finally pushes Gohan over the edge when he crushes Android 16's still-living head underfoot right in front of him. At this, Gohan goes Super Saiyan 2 and promptly annihilates the Cell Jr.'s before wiping the floor with Cell.
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.

At the end of Superman 's "Conduit saga", Conduit sets up television around the deathtrap he stuck Jimmy Olsen in, presumably to invoke this on Superman.
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 Thorgal, Kriss de Valnor takes advantage of Thorgal's amnesia by claiming that he is Shaigan the Merciless, a fellow pirate and her lover. Kriss enslaves Thorgal's wife Aaricia using her and Thorgal's daughter as leverage. Kriss then forces Aaricia to be her personal attendant so that Aaricia has a front row seat as her amnesiac husband makes love to Kriss night after night. It's not enough for Kriss that she finally has Thorgal to herself. No, Kriss has to rub it in Aaricia's face that she's stolen her husband.
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.

In a much more direct way Cognitum forces Blackjack to watch her annihilating several peaceful settlements in order to wriglle some crucial information out of her. Despite a heavy death toll Blackjack holds back, because she knows that with the information Cognitum will do much worse, but she breaks when her friends and loved ones are targeted next.
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!

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.

The agent complies.

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.

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 BIONICLE, Karzahni's Mask of Power has the effect of trapping the target in a vision where they're usually unable to move, and witness horrible alternate futures. In one instance, he made Jaller see what would have happened if he had frozen in place instead of saving his friend Takua, thus allowing the villain Makuta to win. 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.

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.
