Mills: I killed your son because he kidnapped my daughter!
Murad: *slaps Mills* I DON'T CARE WHAT HE DID!It's relatively common that the reason that Alice wants to kill Bob is because Bob killed Charlie. Revenge seems pretty straightforward. But it gets a lot more murky when Charlie was trying to kill Bob and Bob was just defending himself. They were in a war, it was a fight, Charlie surprised Bob at the worst time, it was an accident, the list goes on. He didn't really want to kill Charlie, and would have avoided doing so if possible. It's likely he regrets it greatly. That doesn't matter to Alice, though. Even if Charlie was a zombie actively trying to bite someone and Bob just defended them, Bob has to pay. Related to Avenging the Villain, but in that case Charlie was specifically killed for committing and/or trying to commit evil. This applies when;
— Taken 2
- Gray and Grey Morality is in effect, such as (but not limited to) wars and family feuds where both sides are flawed/justified to an extent at some point.
- Charlie is a good guy.
- Charlie was not himself, being possessed or such.
- Charlie was going about his business when a fatal accident happened, even if he was an Evil Empire mook.
Examples:Anime and Manga
- Enya Geil from Jojos Bizarre Adventure Part 3 wants to get revenge on the heroes for killing his son. Nevermind that his son was a serial murderer and rapist, that he killed the Dead Little Sister of one of the heroes, and that she herself was the one who sent him to fight the heroes in first place, which prompted them to kill him in legitimate defense.
- One episode of Kino's Journey had Kino meet a woman and the man she had hired as a guard as they were about to set out on a journey. She sat with the man for a while, and learned that he had killed her husband several years ago accidentally while robbing his store, and had been reformed and set free by their justice system, on the condition that he make it up to the woman by mutual agreement. It's made clear that his reform and desire to help the woman any way he can in penance for his crime are genuine. They part, and later Kino is riding through the woods when she hears a gunshot- it turns out the woman wasn't so big on the penance idea after all.
- In Samurai Champloo, Jin killed his master Mariya Enshirou in self-defense. Try telling that to Mariya's other students, who are hunting for Jin throughout the series to avenge him. Particularly notable is Not-So-Harmless Villain Ogura Bunta, who managed to hold his own against Jin when he finally encountered him. The shame of his defeat, however, caused Bunta to be Driven to Suicide, according to Jin's Unknown Rival Yukimaru. For his part, Yukimaru doesn't care about their master, and just wants to kill Jin to absorb the reputation of the thousand man killer.
- Kill Bill: Looked at objectively, none of them can be considered good guys considering their careers; but The Bride's former crew killed her innocent new family, which is reason enough for her to kill them all back.
Bud: That woman deserves her revenge, and we all deserve to die. But then again, so does she.
- The Spy Who Loved Me: In the opening scene, James Bond kills Anya's lover, who is trying to kill him at the time. When she finds out about it she vows to kill James. She never goes through with it, giving it up after they manage to foil the villain.
- Star Trek
- Khan in Star Trek II: The Wrath of Khan. Lampshaded even. After Khan explains his beef with Kirk, Chekov says, "Captain Kirk was your host. You repaid his hospitality by trying to steal his ship and murder him!" Khan ignores the point. Khan ignores the fact that Kirk, in simply exiling Khan to his own planet, was more charitable than he had to be given Khan's actions both on the Enterprise and as a fugitive from international justice 300 years ago. Kirk could have easily taken Khan and his people back to Earth and put them in the hands of Federation justice, which might end in a number of ways unfavorable to Khan, his crew, and his girlfriend.
- John Harrison and Kirk in Star Trek Into Darkness. Harrison seeks revenge on Admiral Marcus, and ends up killing Christopher Pike in his attack on the admiral. Pike's death then drives Kirk to swear revenge on Harrison.
- As the page quote shows, Taken 2 is driven by Murad wanting to avenge his son Marko, killed in the original by Retired Badass Bryan for kidnapping his daughter in Paris. Murad doesn't care if Marko worked in a crime ring, and destroyed many young women's lives by forcing them into sex slavery (a fate Bryan's daughter escaped just in time). He just wants to ease his pain by killing the man responsible for Marko's death (and his loved ones).
- The entire plot of Old Boy in a nutshell. Oh Dae-su wants revenge against the man who abducted and imprisoned him for 15 years. Lee Woo-jin in return wants revenge against Oh Dae-su for indirectly driving his sister to suicide.
- In Enűma Eliš, Tiamat does her best to avenge Apsu's death at the hands of the Annunaki, completely ignoring the two small facts that Apsu was actively planning to kill them and that she herself ratted him out to them, allowing a preventive strike.
- In David Eddings' The Redemption of Althalus, when working as a mercenary, Eliar kills the ruler of the city state the mercenaries were attacking. He ends up being captured and Andine, the daughter of said ruler, enacts personal revenge. He gets rescued eventually. And she eventually gets over it. They end up married.
- In A Song of Ice and Fire Lord Karstark wants revenge against Jaime Lannister for killing two of his sons. He does this by killing two of Jaime's relatives who were held captive, killing several men on his own side to get to them. It's pointed out that killing defenseless prisoners and your own allies is not the same as killing an enemy in battle, but the distinction seems lost on him.
- There are other instances where someone (Balon Greyjoy and the Sand Snakes) acknowledges that the people they spent years plotting revenge against are all dead, yet they still want revenge against their House.
- The Martells are seeking vengeance against Ser Gregor Clegane and his liege lord Tywin lannister for murdering Princess Elia Martell and her children during the overthrow of the regime she married into. (True, it was a war and the children were in line to the throne, but it was a particularly brutal and unnecessary murder.) Oberyn Martell is granted the chance to fight Clegane in a duel... and when he loses fair and square, his children start clamoring for revenge against the Lannisters for HIS death, even though Clegane admitted his crimes and died of his wounds anyway, and Lord Tywin is dead from unrelated causes.
- In Diane Duane's novel Spock's World, the Big Bad is seeking revenge on Spock for the death of a mate. What the Big Bad fails to take into account is that the mate took a suicidal risk to get closer to the Big Bad because the mate thought that said character's brooding over the last encounter with Spock was romantic.
- In the Honor Harrington series, Solarian Fleet Admiral Rajampet Rajani states, in no uncertain terms, that he does not care how justified the Manticorans believed they were in killing Admiral Josef Byng, and goes on to say he doesn't care how justified they actually were. His biggest concern is the blow to the Solarian League Navy's prestige their actions have caused and the precedents it could set. This attitude is not helped by the fact that the Manticorans keep Curb Stomping his navy.
- Angel: Turns out that Wesley took Connor to protect him from a False Prophecy stating that "The father will kill the son." Angel accepts this, and tells Wesley so before picking up a Vorpal Pillow. Having one's child sucked into a hell dimension can do that to a person. To be fair, Wesley wasn't the one who sent his son to a hell dimension. The people who did had cut Wesley's throat by that point.
- Farscape: In the very first episode, Crichton accidentally crashes into a ship piloted by Bialar Crais' brother, killing him instantly. Crais becomes insanely obsessed with ferreting out Crichton and killing him, an obsession that lasts most of first season, to the point where eventually Crais loses his job because his priorities are entirely focused on revenge — despite the fact that Crichton continually tries to convince him that it was an accident.
- In an episode where an Evil Sorcerer brings both of them (or, at least, their minds) into his "temple", he does his best to fuel Crais's desire for revenge. Crichton once actually manages to almost convince Crais that it wasn't Crichton's fault by pointing at simple facts: Crichton's Farscape One pod is nowhere near as advanced as a Peacekeeper Prowler (no weapons, minimal defenses, pitiful maneuverability), so there's no way his brother's death could have been intentional. Unfortunately, Malgus chooses this moment to show an image of his brother burning to death, knowing how Crais will react. After Crais becomes a temporary ally, he admits that his own career was waning, and he was projecting this frustration onto his brother's "killer".
- Once Upon a Time: This defined the relationship between Captain Hook and Rumplestilskin. Hook had fallen in love with Rumple's wife, Milah. Rather than leave a Dear John letter, Milah and Hook faked her kidnapping and let the then-human Rumplestilskin and his son believe she had been murdered by pirates. When the current Dark One Rumplestilskin found out about the deception, however, he murdered Milah and cut off Hook's hand. Swearing revenge, Hook vowed to find a way to kill him. However, since Rumplestilskin is near-unstoppable while the Dark One, most of Hook's attempts have involved hurting Rumplestilskin's true love, Belle, who has never done anything to Hook.
- ''Revenge: Victoria Grayson wants retribution against Emily for what happened to her family, actual or perceived. Thing is, after what Emily went through, and how much of it for which she was responsible, she had it coming, especially given that her season 3 finale fate of being committed to an asylum was exactly what she did to years ago young Emily.
- "Pilot" starts with a group of militiamen trying to take Ben Matheson into custody peacefully, and he's even willing enough to go; all he asks is a few moments to make arrangements for someone to care for his children, which the militia leader grants him. Unfortunately, his son Danny overreacts and rouses half the settlement to resisting (and dying). The militia may be bad guys, but this particular scene was a pretty clear cut case of self-defense. The heroes don't see it that way.
- "No Quarter" has one militia soldier guilty of it as well, in a far more blatant and infuriating fashion. Danny Matheson kills one of the militiamen (Templeton) and the friend of this militiaman (Private Richards) gives this speech about how "that soldier had a name and a family", clearly trying to up the guilt for Danny's "senseless slaughter". When Danny coldly points out that said soldier killed Danny's father first, just seconds earlier, as the first shot fired in the battle, the soldier's friend simply chuckles and says, "Well, let's be honest, that was no big loss."
- Soap: Danny wants to kill Burt, his stepfather, because he killed his father. Burt also feels horrendously guilty over this fact, but it turns out that Burt only killed him in self-defense. Danny eventually agrees with him.
- Star Trek: The Next Generation: In "The Battle", the Ferengi DaiMon Bok wants to avenge his son, whose ship had been destroyed by Captain Picard during the Battle of Maxia, even though Picard destroyed the ship entirely out of defense.
- The Walking Dead has The Governor get a vendetta attitude about Michonne because she finished off his zombie daughter, even though he had previously sent men out to kill her simply for not buying into his false utopia (without which it is unlikely she would have returned), and even after acknowledging his daughter was already dead.
- In The Lizzie Bennet Diaries, Lydia frequently insulted Lizzie, making comments about how she would need to change if she wanted a boyfriend. But when Lizzie bluntly told her that she would need to change her ways to have a successful career (something Lydia wasn't interested in), Lydia was offended and remained furious for a long time, viciously criticizing Lizzie and guilt-tripping her about Lizzie's fear of abandonment and lack of people skills.
- In American Dad! episode "Escape from Pearl Bailey": Steve get's revenge on a group of popular girls after he finds they smeared his girlfriend in a class political campaign. He later finds out that it was actually his friends who did the smear, and tries to explain this to the now angry popular kids, which doesn't matter as Steve had disfigured one girl and given the other an STD all for a few insults. The kids proceed to beat up both Steve and his friends.
- In the X-Men: Evolution episode "Blind Alley", Mystique pretends to be Scott's brother Alex, supposedly stuck in Mexico after losing his passport, in order to lure Scott out on his own, knocking him out and leaving him stuck in the middle of the Mexican desert without his glasses to stop his eyes, saying "That's payback!" after Scott let her get captured inside a military base in "Day of Recovery". However Scott did that because she had abducted Professor X and impersonated him throughout the two-part episode "Day of Reckoning", and refused to divulge the location of the real Professor X. Note that when he managed to find his way to the city, she intended to knock him out and do it again, somewhere even more remote.
- The Dexter's Laboratory segment Mandarker cements Mandark's motive for outshining Dexter, as revenge for destroying his lab (through Dee Dee). But while it does a good job creating sympathy for Mandark, what it fails to mention is that Dexter did that in retaliation for Mandark forcing him to shut down his lab. A later episode reveals that Mandark's real motive is payback for Dexter making fun of his original name - "Susan".
