Motive Rant

A standard ingredient of The Summation in any Cop Show, Police Procedural, Law Procedural or Mystery of the Week. After the detective has shown without doubt who the killer is, the killer will launch into a long, self-righteous (or remorseful) monologue explaining why exactly they did what they did. This both serves as confession and allows the writers to explain how this solution to the mystery makes sense, even if it's often a "He called my mother a bad name, he deserved to die!" kind of sense. It's often the only way to make the perp's feelings obey the Rule of Perception, since they must be hidden until the crime is solved.

This is a good place for a We Are Everywhere moment.

The detective will then give them the Book'em, Danno in response.

Oh, and it doesn't matter if the character's a timid librarian, a jolly bartender, a butch farmhand, what-have-you, when they are revealed to be the killer they all suddenly snap into the same cookie-cutter personality type: bitter, twisted loony.

In real life, pretty much any motive rant is replaced with "I want to see my lawyer".

Also in real life, a criminal that's cornered tends to do things like socking the other guy in the face and running away. This never happens in television, despite the detective being so often the only other person in the room with the criminal.

This tropes doesn't necessarily have to be applied in the interrogation room, however. It could be given by the killer when he thinks that he's got the Final Girl at his mercy, or when he's explaining his motivations to an accomplice. All that matters is that the killer explains just why he's committing his crime in the first place.

The Motive Rant is the intended result of The Perry Mason Method. It's often part of a Villainous Breakdown. The Hero might respond by saying Shut UP, Hannibal.

Anime and Manga
" What is justice!!?  That is surely good! It is a beautiful thing! Undeniably so! But is what is good the same as what is just!? No!!! Living peaceably without  ...THAT IS EVIL!!!!"
 * Every episode of Detective Conan ends with a Motive Rant in which the culprit explains why did he or she do it. Sometimes countered by a motive rant from another person that completely destroys their motives and breaks the culprit completely.
 * The Kindaichi Case Files also does so. More often than not, the rant makes the killer a lot more sympathetic than his/her actions do.
 * Kaitou Saint Tail has a tendency to make her "victims" go into Motive Rants when she escapes with their already stolen goods.
 * Light has one in the last episode of Death Note, which is also a bit of a Hannibal Lecture about how the world needs Kira and if they stop him the world will only go back to the rotten way it was, and  The latter was actually true.
 * So was the former, at least about the world returning to its pre-Kira state - according to Ohba,, proving that it was only fear keeping people in line.
 * Happens a lot in Majin Tantei Nougami Neuro.
 * At the end of the first season of Darker than Black, a leader of The Syndicate gives one of these to Kirihara.
 * In chapter 385 of Bleach,  finally cracks and explains his motives  . By the way, the "cracks" part is appropriate;.


 * This happens several times throughout Liar Game.
 * Naruto: Itachi gives his Motive Rant to Sasuke in episode 136 of Shippuden.
 * Happens once in Rebuild of Evangelion 2.0: when Shinji almost trashes NERV HQ for an otherwise completely justified reason, Gendo explains why he's such a bastard: he believes that he can only achieve his desires if he's willing to sacrifice everything and use his own strength.
 * Gendo gets a good one at the end of the Evangelion manga as well. Notable because he does it, and because he explains in a starightforward, non-symbolism laden manner exactly how he feels towards Shinji:
 * Kazemakase Tsukikage Ran: Once exposed, Mei tries to justify her drug business with one.

Comic Books

 * In Batman #650,  was furious that Batman thought his Roaring Rampage of Revenge was all about.


 * Watchmen has one of the best Motive Rants of all time, where the surprise villain,, reveals his incredibly elaborate plan while ignoring three separate people  , and not only did he  ''.
 * Sin City features rants by almost every antagonist before they meet their fates.
 * Sin City features rants by almost every antagonist before they meet their fates.
 * Sin City features rants by almost every antagonist before they meet their fates.

Film
"Gloria: You can't go around killing people just because you don't like them! Grace: That was something my therapist and I could never agree on."
 * A fabulous comedic one by Debbie Jellinsky in Addams Family Values. "So I killed. So I maimed. So I destroyed one innocent life after another. Aren't I a human being? Don't I yearn, and ache, and shop? Don't I deserve love...and jewelry?"
 * gave a melodramatic but effective example of this in After the Thin Man, in which he plays a painfully bland "nice guy" for 90% of the film, only for us to watch his character flip out in a fantastic performance in the final denouement.
 * In the movie version of Goblet of Fire, Barty Crouch Jr has one rather amusing flashback motive rant.
 * Draco Malfoy has one of these in Half-Blood Prince
 * Played straight - and highly effectively - by Jack Nicholson at the climax of A Few Good Men.
 * This one does vary from the classic definition in that the actual confession comes at the end of the rant.
 * Averted in the opening scene of Keeping Mum; when the police question her about the bodies, she just calmly admits to it as if murdering them was the obvious solution.
 * Summed up rather nicely in this conversation between Gloria and Grace (the killer):

"Sugai: Sato. He might as well be an American. His kind only cares about money. Conklin: Oh yeah, what are you in it for? Love? Sugai: I was ten years old when the B-29 came. My family lived underground for three days. When we came up, the city was gone. Then the heat brought rain. Black rain. You made the rain BLACK. You shoved your values down our throats until we forgot who we were. You created Sato and the thousands like him. I'm paying you back."
 * Parodied in the 1947 comedy Copacabana. Lionel Q. Deveraux (Groucho Marx) is on trial for murdering his partner's non-existent stage persona. He breaks down on the stand "I didn't do it, I tell you! I didn't do it and what's more, I'm glad I didn't do it! And if I had it all to not do over again, I wouldn't do it again!"
 * John Doe, the murderer in Se7en, gave a prime example of one to the detectives while in their car.
 * The following conversation between Detective Conklin and the elder Yakuza boss Sugai in Black Rain is a very effective example of a subdued rant.

""I see a place where people get on and off the freeway. On and off. Off and On. All day, all night. Soon where Toontown once stood will be a string of gas stations. Inexpensive motels, restaurants that serve rapidly prepared food, tire salons, automobile dealerships, and wonderful, wonderful billboards reaching as far as the eye can see. My God, it'll be beautiful.""
 * Judge Doom has a hilarious one in Who Framed Roger Rabbit?.

"Waters:Them Nazis ain't all crazy. Whole lot of people just can't seem to fit in to where things seem to be going. Like you, CJ. See, the Black race can't afford you no more. There used to be a time, we'd see someone like you singin', clownin', yassuh-bossin'... and we wouldn't do anything. Folks liked that. You were good. Homey kind of nigger. When they needed somebody to mistreat, call a name or two, they paraded you. Reminded them of the good old days. Not no more. The day of the Geechee is gone, boy. And you're going with it."
 * Mugatu explodes into a motive rant at the end of Zoolander that accidentally presses Derek's Berserk Button by claiming that Derek "only has one look".
 * Sgt. Waters has two very effective ones in A Soldier's Story:

"Mrs Lintott: I'm reluctant at this stage in the game to expose you to new ideas, but having taught you all history on a strictly non-gender-orientated basis I just wonder whether it occurs to any of you how dispiriting this can be? [...] History's not such a frolic for women as it is for men. Why should it be? They never get round the conference table. In 1919, for instance, they just arranged the flowers then gracefully retired. History is a commentary on the various and continuing incapabilities of men. What is history? History is women following behind with the bucket."
 * A rare non-villainous example with Mrs Lintott from The History Boys, addressed to her all-male class and colleagues.

": You were not quite right about the suburbs. Here all you have to do is take one step out of line. You paint your house the wrong shade of pink, you buy the wrong kind of car, you make one or two human sacrifices...Then when you walk down the street, everybody says "Oh, there goes the weirdo!" Ray: Why did you come here?
 * has a minor one in Mystery Team.
 * There's a cut one of these in an alternate ending to The Burbs.
 * I came as you did. For the quiet! For the privacy! The good life! The convenient shopping with always plenty of ample free parking! But everywhere I always met all this suspicion and distrust!
 * It's true. In L.A. no one ever said anything!"

"I do love a good joke, and this is the best ever. A joke on the children!"
 * Halloween III has a classic one from, although it's not so much a "rant" as a "calm explanation"

Literature
""I am the law, and I am the judge! I am the oppressed, and there is the oppressor! Through him I have lost all that I loved, cherished, and venerated -- country, wife, children, father, and mother. I saw all perish! All that I hate is there! Say no more!""
 * The Duumvirate asks for this before they kill important enemies.
 * launches into one of these when he's finally questioned hard enough by one of the characters near the end of The Brothers Karamazov. He's not self-righteous or loony about it. He actually comes off as calm and collected, as if what he did is the most natural thing in the world. Given all the rants and profound conversations we've experienced thus far, he's almost justified.
 * Played straight, justified, and used to incredibly disturbing and offensive effect in Gaudy Night, the penultimate Lord Peter Wimsey novel and arguably the only one where the villain is ideologically motivated.
 * Since Tang Chinese law required the criminal to confess for a conviction, Judge Dee listens to a lot of these.
 * Played straight by The Mule when he gets caught in Foundation and Empire, then subverted as he proudly points out that he still has the upper hand, and leaves because he has a galaxy to rule.
 * The villain of The Name of the Rose by Umberto Eco gets an extended Motive Rant, in which he explains in detail why he was willing to kill to keep hidden.
 * Major Grodin Tierce goes into one of these during his Villainous Breakdown.
 * In the last book of the New Jedi Order, Big Bad launches into an extended one of these to Jaina Solo. Notably, while   seems to think that he's portraying himself as a sympathetic Woobie, Destroyer of Worlds, Jaina just thinks he's nuts. The readership agrees with her.
 * Discworld:
 * The thief of the Scone of Stone in The Fifth Elephant gets one.
 * does one in Maskerade, listing all the things he hates about opera after being fatally "stabbed". The final complaint is how long it always takes people to die.
 * In John C. Wright's The Golden Transcendence,  gives a multi-page, firebreathing rant on why he/she felt like destroying society...and is unpleasantly surprised to find that no one cares.
 * Subverted chillingly in Benito Cereno. When the instigator of the slave revolt aboard the ship is eventually found out, he never speaks a word about his motivations or tries to justify his actions.
 * Howard Roark has kind of the most epic one ever in The Fountainhead when he explains It goes on for pages and pages. And he says it all incredibly calmly and matter-of-factly.
 * In Victor Hugo's The Hunchback of Notre Dame, Frollo subjects Esmeralda to a rant about his obsession with her and why she has to love him back. It very much showcases his Villainous Breakdown.
 * Twenty Thousand Leagues Under the Sea: Captain Nemo says one to The Professor Aronnax when he tries to convince him not to Kick the Dog, and could be considered the beginning of Nemo's Villainous Breakdown:

Live-Action TV
"Drebin: Why'd you do it?!"
 * The killer in Perry Mason almost always does the motive rant on the stand, after which all charges against Perry's client are dismissed. You can tell the exact instant the culprit will stop denying and begin the motive rant based on the music changing. It is so necessary to the formula for the motive rant to occur on the stand that you can identify the killer instantly when Mason reserves the right to recall a witness.
 * On CSI and its spinoffs, motive rants occur in the interrogation room.
 * Averted in one episode of CSI: Miami. At the very end of the episode, as a serial sniper is being taken away by the police, he asks Horatio "Don't you want to know why I did it?". Horatio simply replies "You're evil, you enjoy death, I hope you enjoy your own."
 * Also averted in an episode of CSI New York. The killer seemed to have no real connection to the victim, who was a young woman in her early twenties, and he didn't tell them why he did it. Lindsey, who was shaken up because of the fact that she shared the victim's age and home state, visited him in prison just so she could ask him again why he did it. He just asks her "You came here just for that?" and puts the phone down.
 * Averted in an episode of Bones; when the criminal started explaining exactly why he'd turned to cannibalism, Brennan promptly knocked him unconscious, saying that nobody wanted to hear the "psycho speech."
 * Parodied in an episode of Police Squad!:

"Hawkeye: I did it, and I'm glad I did it! I hated them all. I can't remember their names, but I hated them.... B.J.: Why did you kill the pigs? Hawkeye: They were about to squeal!"
 * iCarly: Missy gives one to Sam, as part of her latching onto the Villain Ball. It ruins the plan because it turns Sam from questioning if Missy even was trying to get rid of her, into sure of it, and decided to bring Freddie in to help her.
 * Every Law and Order. SVU really stretched it when a ten-year-old had such a rant explaining his motivation (it was 'cause he saw it on TV, see). Like in Perry Mason, the background music is often the cue.
 * Interestingly used on an episode where a man is on trial for manslaughter; specifically, he a trained psychologist accused of pushing his daughter-in-law to suicide. On the witness stand, he confesses to murder. The problem being that if he's found innocent of manslaughter, he can't be tried for murder for the same crime; double jeopardy. (He's convicted of man 1, and Adam Schiff points out that if he was guilty of murder, he just got himself "one hell of a plea deal.")
 * CI has raised to the level of an art form with the Hand Wave/Justification that causing Motive Rants is what Goren specializes in.
 * Criminal Intent has also subverted the rant on one occasion when a suspect is driven to confessing, but it turns out that she didn't really do it.
 * Also subverted in another episode (where the overbearing nature of her husband causes a woman to kill two her children in a failed mass-suicide attempt) where Goren sucessfully caused the husband to break into a Motive Rant, but it ends up being all for naught because he never really did anything illegal.
 * Subverted at first in the Grand Finale of The Fugitive, where.
 * Mostly averted in Angel, where most revealed enemies tended to give a one liner before trying to kill him, or not have any idea who he was and just trying to kill him. Nevertheless Connor gave one near the end of season four. Somewhat notable for being delivered solely to someone in a Convenient Coma and being a despairing rant rather than a self-righteous justification. Jasmine got a shorter one, shortly before that.
 * The secret Big Bad of season two of Veronica Mars,  gave a particularly jarring one of these. In the last ten minutes or so he suddenly snapped into a pure Diabolical Mastermind mentality, despite this being completely at odds with his established character and his actual motive. Then, when he finished his speech and things went wrong, he reverted to his original personality. The worst part is that it was just about believable that he would do, well, some of things he did, with his established character, and if he had stayed in character instead of channeling a Bond villain it might not have seemed so unbelievable.
 * Subverted in an episode of Psych. After The Summation, the murderer simply said "I have nothing to say. Speak to my lawyer."
 * A very common feature of Columbo episodes.
 * Hilarious subversion in Pushing Daisies when the killer delivers a crazed speech detailing his motivation - which the protagonists can't hear at all, because they're trapped in soundproof bags.
 * Generally, the show didn't do these; because it had a narrator to explain the motives, there was no need for the actual killers to do so.
 * Alias has a neat treatment of the trope in the season one episode "The Coming Darkness." Sloane muses to Jack how he's been having a pretty bad week (due in no small part to Sydney's and Jack's efforts), and reminisces at length about a time when he felt "a coming darkness". He mentions that before he and Jack even met, he had a "perfect moment"... and though the CIA hadn't yet betrayed him and the wife he hadn't even met yet had not yet been diagnosed with cancer, he felt what he called a "coming darkness". So, he sums up: whenever things go very badly, he just reminds himself he could see it coming all along. And then he coldly hisses that he wants one of the things vexing him dead before the weekend.
 * Lily in How I Met Your Mother has one of these in "The Front Porch", imitating the A Few Good Men example.
 * In one episode of Star Trek: Deep Space Nine, Dax (Ezri, not Jadzia) is chasing a serial killer who turns out to be a Vulcan. After catching up with him, she asks why he did it. In an aversion, he responds "Because logic demanded it.", the Vulcan version of "God made me do it." Although, when you think about it, this is an explanation - kinda.
 * In the musical It's A Bird, It's A Plane, It's Superman Dr. Abner Sedgwick explains his motive in song.
 * Subverted in Misfits when the villain makes quite a valiant attempt to explain/justify her actions, but Nathan is playing his music over her rant and keeps interrupting her so the audience hears very little of what she's saying. All we know for sure is that her crusade had something to do with being teased at school for being a virgin.
 * Parodied in That Mitchell and Webb Look when the detective manipulates a woman into doing "the evil voice" and eventually an entire Motive Rant that ends in her suicide. He says that it's better this way, as he didn't have any other evidence and not all courts accept the "evil voice". He also accidentally provokes someone into giving one, identical in tone to the first, except about not flushing the toilet instead of murder.
 * Criminal Minds doesn't have a huge number of these because episodes often don't show the killer after they've been caught and quite frequently they end up getting killed rather than arrested, but "The Fox" and "Poison" both had pretty chilling ones. It was also subverted in another episode where the murderer himself said that he didn't know what made him kill.
 * Possibly Fridge Brilliance at work, as a key premise of profiling is that serial offenders are really acting out their inner demons and insecurities, whatever superficial rationale they might layer on top of that. Any Motive Rant most perps would be capable of articulating is only their self-justification, not their motive.
 * Assuming the profilers are doing their jobs, they'll have deduced the content of an offender's Motive Rant before they actually meet up with the perpetrator.
 * For example, in "Masterpiece" the killer turned himself in to police after kidnapping five people, saying they'll die if not found in a few hours. The team finds where they're being held and leave, except for Rossi, who continues interviewing the killer. At this point, the killer reveals that the location is a trap, and launches into a full-on motive rant, revealing that Rossi had arrested his brother (also a serial killer) and he'd wanted revenge. Cue Hotch calling to tell Rossi that the trap was right where he'd said it'd be, and all the victims are fine. Rossi'd guessed the trap, but intentionally triggered the motive rant to get the killer to admit to his other killings on tape.
 * Castle gives one of these for the killer in one episode, identifying his motives well enough that the killer gets caught up in the story and confirms it's exactly how he felt.
 * Castle alternates between this and just asking to see their lawyer.
 * Parodied in the M*A*S*H episode involving an allegedly Fair Play Whodunnit novel with the last pages missing. After all episode spent with the MASH personnel discussing and shooting down their theories, and then Word of God from the author turning out to be wrong, Hawkeye "confessed":

Music

 * Subverted in Bruce Springsteen's song "Nebraska"; right before being executed, Charles Starkweather acknowledges that people want to know why he became a killer, but all he offers as an explanation is, "I guess there's just a meanness in this world." This is artistic license, however, as the real Starkweather didn't say that.

Theatre
"Iago: Demand me nothing. What you know, you know. From this moment forward I never will speak word."
 * Famously subverted in Shakespeare's Othello. After Iago is captured and Othello demands to know why he tricked him into killing his own wife (something all the readers would like to know as well):

"Salarino: Why, I am sure, if he forfeit, thou wilt not take his flesh: what's that good for? Shylock: To bait fish withal: if it will feed nothing else, it will feed my revenge. He hath disgraced me, and hindered me half a million; laughed at my losses, mocked at my gains, scorned my nation, thwarted my bargains, cooled my friends, heated mine enemies; and what's his reason? I am a Jew. Hath not a Jew eyes? hath not a Jew hands, organs, dimensions, senses, affections, passions? fed with the same food, hurt with the same weapons, subject to the same diseases, healed by the same means, warmed and cooled by the same winter and summer, as a Christian is? If you prick us, do we not bleed? if you tickle us, do we not laugh? if you poison us, do we not die? and if you wrong us, shall we not revenge? If we are like you in the rest, we will resemble you in that. If a Jew wrong a Christian, what is his humility? Revenge. If a Christian wrong a Jew, what should his sufferance be by Christian example? Why, revenge. The villany you teach me, I will execute, and it shall go hard but I will better the instruction."
 * Early on in the play, Iago had ranted that Cassio was promoted ahead of him, despite Cassio being newer to the army and Iago having served faithfully for much of his life. The rant also reveals that Iago is racist, and this, combined with his anger at not being promoted, is what caused him to seek revenge on Othello. He did it in a way that allowed him to act on both his reasons for hating Othello: he set up Cassio as someone Othello couldn't trust, and targeted Othello's marriage to Desdemona because he—and many other characters in the play—objected to the idea of a black man marrying a white woman.
 * Shakespeare did this in The Merchant of Venice:


 * In Chicago, when Roxie Hart is first being interrogated by the police, she confesses that she shot the victim because he was going to leave her and she would happily do it again. This means her Amoral Attorney has some really clever explaining to do in order to get her acquitted of murder.

Video Games
"Big Boss: I can say one nice thing about the Cobras: they mostly had the decency not to spew out their life stories, before or after I fought them."
 * It seems like all of the witnesses in Phoenix Wright: Ace Attorney and its sequels do this at least once. Once Phoenix starts to unravel their testimonies, every witness goes nuts and starts raving about their motive and how perfect their plan was (or, if they happen to be very pompous or arrogant, they become very quiet and submissive). This even applies on a lesser scale to the witnesses who don't end up being the murderer, in which case they usually just freak out and tell the truth, rather than lying as they had until then. The most notable example is when . In fact, at one point Phoenix notices something is amiss when a witness doesn't go into a Motive Rant.
 * An exception is
 * Boss characters, (and many NPCs) from the Metal Gear Solid games have a tendency to do this either just before fighting Snake or with their last breath after having been fatally wounded by him. The Quirky Miniboss Squad from the third game mostly avoided this, but The Boss (their leader) made up for it in spades. Fan Web Comic The Last Days of Foxhound noticed and commented on this.


 * The Beauty and The Beast unit from Metal Gear Solid 4 also avoid this, due to its members being completely Ax Crazy. "Luckily," Drebin is happy to do this on their behalf via Codec every time Snake defeats one of them.
 * The Boss also has a monlogue before the final duel with her, in which she explains everything she had given up for her country, and how pointless it had been rendered by the Cold War (although she doesn't rant so much as just get it all off of her chest).
 * Mass Effect has explain, twice even, exactly why he's working with
 * Jin Kazama in Tekken 6.
 * At the end of Rainbow Six: Vegas 2, Big Bad
 * Doesn't help that.
 * In the penultimate mission of Splinter Cell: Chaos Theory,  gives a pretty impressive rant on what drove him to fund terrorists and try to start World War III. He then tries to pull a "I Surrender, Suckers", and things go downhill...
 * At the end of Conviction  does the same, talking about how the President was going to pull funding from   and go soft on terrorism.
 * Ganondorf was just jealous of Hyrule's wind in Wind Waker.
 * In a variant, though, there's he's not gloating. He's just - nostalgic? bitter? remorseful? detached? Take your pick.
 * Modern Warfare 2. 30,000 men. You know the one.
 * Say what you will about Shepherd having crossed the Moral Event Horizon but after his simple but passionate statements about the sacrifices he has had to make you can no longer look at him using simple Black and White morality.
 * In The Godfather game,  gives you one as you're hunting him down. Various important mobsters also give short ones if you manage to grab and interrogate them.
 * Tsukihime, when it seems Hisui's True Ending has been played out...
 * gets one as the player travels his dungeon in Persona 4. At the very end, he's given a Shut UP, Hannibal by the protagonists and called out for his senseless motives.
 * Terumi Yuuki gives one mostly when unveiling Mu-12, stating that he thinks the world are nothing but lies, the only truth out there is despair and he sure as hell will show them by having Mu-12 destroy Master Unit Amaterasu.

Web Original
"Melina: You know? I never really liked men. Do you know why? It's because they always WANT something. Did you know that? Well, obviously you do. Men constantly WANT. They want to hold you, touch you, kiss you. They want to make you THEIRS. But? I never really liked that you know. That's why, instead of letting them TAKE whatever they want? I decided to WANT and TAKE from them first!"
 * After in Kate Modern: Precious Blood has been revealed as the murderer by a group of unarmed individuals in the middle of nowhere, he for some reason feels compelled to explain at great length the full extent of his crimes  on camera. In his defense, he later admits to having been "a bit off [his] face" at the time.
 * Depraved Bisexual and Mariavel Varella clone Melina Frost does this in Survival of the Fittest version three before attacking Dacey Ashcroft and Herman Johnson. Ironically, Dacey isn't a guy.

Western Animation
"I like to watch them. They fill me with joy. The first I felt it I thought I was going to die. I said to the Red Bull I must have them, all of them, all there are. For nothing makes me happy but their shining and their grace. So the Red Bull caught them. Each time I see the unicorns, my unicorns, it is like that morning in the woods and I am truly young, in spite of myself."
 * The Simpsons did it. In "Sideshow Bob Roberts", when Lisa insinuates that Bob is too stupid to have rigged an election and claims Bob's Rush Limbaugh look-alike accomplice is the real brains of the operation, Bob flies into a rant about how he (and only he) had the brains to orchestrate everything, parodying the A Few Good Men quote above. He is then promptly taken to jail for "all that stuff [he] did" with unusual expediency for the Springfield police.
 * In Transformers Animated, Wasp breaks into one in "Where Is Thy Sting," justifying his revenge on Bumblebee. While Wasp does have every right to be pissed, Bumblebee isn't the one who framed him...
 * Practically every Scooby Doo story ever written ends with one of these, once the villain's been unmasked. And of course, he would've gotten away with it too, if it weren't for You Meddling Kids.
 * Almost; usually, it's the kids who reveal motive for him/her.
 * Parodied in Kick Buttowski, while telling the class about something amazing he did, he quickly gets questions from the not so convinced teacher and Kendall, only to have the interrupted by Jackie who goes into the "You can't handle the truth" speech... only for everyone to tire of her ("Not this again...") and lower a sound-proof glass dome around her desk.
 * One of the most notable examples in western animation comes from The Last Unicorn when King Haggard (who is voiced by the legendary Christopher Lee) explains to Lady Amalthea, a unicorn transformed into a human, why he has captured all the other unicorns.


 * The Rugrats episode "The Trial" has Angelica revealing that she did break Tommy's lamp after failing to pin it on Chuckie, Phil and/or Lil. It's a bit of Karmic Retribution as Angelica starts gloating that, even though she confessed, they couldn't do anything because they can't talk... forgetting that she can. And Didi and Betty heard the whole thing.

"Davros: "When I press this switch, I will die. The poison in that projectile injector will kill in a moment. It is a perfect, efficient, killing machine. It will be painless they say. They tell me they know the pain I am in, as if they could! And that just by pressing this switch I will end that suffering forever. They say I should be the one to do it, but they are weak. They can not bring themselves to look at me, let alone kill me! They hesitate, they fear me! Even when I'm like this, and they have their perfect, pure, strong bodies, they fear me! And well they should! I am no longer like them, I am above them! I have the ultimate power, the power of life and death! This... body, this... is my dominion. Mine to command, no one else's! I can sense them out there in the corridor, cowering. Not daring to speak. They are the frail ones. They are the crippled. They are the ones without choice. They! Will! Die! They will lose this war and they will die! I could join them in defeat and death, but if I survive! If I survive, something stronger will emerge. A new race, the supreme power in the universe! I will not press this switch, I will not cower, I will not die! I! will! not! die! THIS! IS! NOT! THE! END! THIS! IS! ONLY! [ Dramatic Pause ] 'THE BEGINNING!'"
 * The Big Finish audio play Davros has a spectacular Motive Rant for the title character. Starts out as a menacing whisper, but at the end, well...


 * An interactive Canadian museum exhibit about forensic science challenges visitors to solve a young woman's murder. If you correctly determine who the killer is and what evidence proves it, you'll get to see the killer's Motive Rant.
 * While not a criminal, Danish comedian Anders Matthesen wins an award for being a role model, and throws a Motive Rant in the direction of the secretary of education (Bertel Haarder), who accused him of being an Anti-Hero: "Bertel, blow me! I'm not a fucking anti-hero. What are you talking about? Anti-hero, I don't know what the fuck you're thinking? I've always said, which the people who listen to be and have voted for me can confirm, that I believe that you shouldn't do drugs, you shouldn't waste your own time or other people's time, that you don't do violence and that you always do your fucking best, which I think a real role model should be doing"
