Teach Him Anger

"Kaname: Just think of this! If you lose, the bad guys are gonna rip off all my clothes, play around with my body then kill me when they're done! Imagine that happening to me!... You'd hate it, right?

Sousuke: Right.

Kaname: Does it make you mad?

Sousoke: I guess so.

Kaname: He's trying to do these things to me! You can't let him do that, can you?

Sousuke: NO!!!

Kaname: Then point your gun at him!"

- Full Metal Panic

Kindness is a highly valuable trait in people, but, if taken to extremes, also a potentially dangerous one to have. In episodes where the Nice Guy and Friend to All Living Things will unavoidably have to face danger, friends will try to teach them assertiveness, a few self defense moves, or actual fighting techniques to face threats. The problem lies in that they are too timid, half hearted, Weak Willed or kind to avoid their Extreme Doormat tendencies, much less actually learn to fight.

The solution is to teach him or her anger and rage; rather than dealing with their anger in a healthy way (or more likely, sublimating it) instead channel it into their words and fists. In extreme cases, even going so far as to instill a killer instinct.

This can have two outcomes, one good and one bad.

The good outcome results in the character taking a level in badass and gaining a backbone along with the combat skills thanks to this training, which may take the form of anything from simple self defense classes to outright maddening them into misanthropy. Their nature and demeanor as a kind/caring/friendly person will otherwise remain unchanged, but now they'll stand up for themselves and the weak rather than simply caring for them.

The bad outcome happens when they learn anger only too well. In some cases, these kind and caring pacifists subconsciously knew they were carefully balanced over a dormant volcano of potential violence and chose to keep it dormant at all costs. And then their friends went and woke it up. If Phlebotinum is involved then it is likely paired with An Aesop against changing others to suit you...because they'll turn into Brainwashed and Crazy dynamos of destruction who revel in their new Super Powered Evil Side. There may be a cry of "What Have I Become"/"What Have I Done" if someone they care for is hurt, or killed!

On the bright side, these usually end in Pygmalion Snapback.

Anime and Manga

 * Full Metal Panic - The rugby episode...
 * Baam, for the life of him, could not conceive any reason why people would fight. The Rachel asked him what he'd do if somebody hurt her. He then understands.
 * Headon takes this to the next level when he tells Baam that he won't see Rachel ever again if he doesn't take that test. This is more a case of evoking Baam's greatest fear. Headon being Headon,
 * Well, in Katekyo Hitman Reborn, this is pretty much what Reborn tries to teach Tsuna, which is part of his process of growing out of being a total loser and becoming a real man. The Dying Will Bullets, to put it simply, either put Tsuna into a determined, unstoppable rage, or give him cold, calculating killer instinct. This is mainly played as having good results, with Tsuna gaining a backbone and the strength to protect his "family."
 * There's a Star Wars manga (yes, Star Wars manga, and not just of the movies, although it's non-canon) where Darth Vader slaughters a colony of hidden Jedi and spares the last one, a rather young boy, because Force Sensitivity plus incredible anger equals a good Sith apprentice. So Vader takes the boy back and finds that while Tao attacks him on command, for whatever reason even reminding the boy that Vader killed his family and razed his world doesn't make him use his hatred. ...It's a rather weird story.
 * This sounds like what would have happened if Otakus had written The Force Unleashed's script...
 * Gohan pretty much goes through this in the Cell saga of Dragonball Z. It has good results when he finally achieves the Super Saiyan state, but when Cell forces him to go Super Saiyan 2 so he can have a worthy fight the opposite happens. Crowning Moment of Awesome yes, but Gohan's actions later on cause Goku to make a Heroic Sacrifice.
 * A large part of Gohan's training with both Piccolo and Goku is this. It finally culminates with Android 16 summarizing it in a succinct speech right before Cell kills him. The result gives Gohan access the Super Saiyan 2 and the loss of his childhood innocence, only for him to forget how to get the most out of channeling his rage 7 years later when it's needed again, and simply being out of shape.
 * Zane in Yu-Gi-Oh GX. After a string of crippling defeats, he ends up on the brink of losing to a comic relief opponent while the crowd makes fun of him, and his manager coaxes him to let go of his "failed" ideals that got him to this point. The kid goes berserk, summoning a monster that almost destroys the arena and takes out his opponent in one turn. The whole point of this duel was for Zane's manager to convince him to reform and turn his career around, but if his reaction to Zane's gambit is a good indication, this wasn't quite what he had in mind.
 * In Fist of the North Star, Shin unintentionally does this to Kenshiro. After thoroughly defeating him, Shin gloats to Kenshiro that the difference between the two is that Shin is filled with ambition and Kenshiro isn't. Kenshiro took this to heart, and by the second encounter it's the other way around, with Kenshiro burning with anger and ambition to save Yuria against a broken Shin from The fight barely lasted 10 minutes.
 * One Axis Powers Hetalia strip has Greece trying to get the polite and soft-spoken Japan to become angry. He succeeds by telling him to think about wasting his money.
 * Basically the conspiracy's goal in the 2003 anime version of Fullmetal Alchemist, which seeks to make a powerful alchemist angry, callous or desperate enough where they're willing to . This approaches Break the Cutie levels for Reluctant Warriors Ed & Al.
 * In Pluto, Dr. Tenma teaches Atom hatred in a desperate attempt to


 * As it would turn out, Tenma also gave Atom presumably to give him more hatred. As it turns out.
 * Guilty's training of Ikki in Saint Seiya, giving him Training From Hell while goes to extreme levels to anger him to use the Phoenix Cloth. Ikki endures it all until Guilty accidentally kills his daughter Esmeralda during training, making him snap and kill Guilty in a fit of rage (to Guilty's glee), earning the Cloth in the process.
 * The whole first half or more of Trigun is about this trope being pushed on Vash, the villains trying to make him snap and kill. Knives' whole life has been theoretically devoted to a Roaring Rampage of Revenge against the human race, and he wants his brother to join him, or failing that to stop being so high-and-mighty.
 * Wolfwood, who isn't a villain, is even more determined on this front; in the manga this leads to an epic moment where he pulls Vash's gun against his own face and demands, "shoot." Saying it would be worth his life if Vash would submit to reality and take up his role.
 * Vash does have plenty of anger, and on occasions like 'Diablo' it proves seriously scary. He wins the really important things without it, though. Both versions.

Comicbooks

 * Bruce Banner has Aesop Amnesia about this. The Hulk, of course, doesn't need to be taught anger. But the Hulk is usually considered a product of Banner's repressed rage, childhood abuse, and generally screwed-up psyche. Trying to control or get rid of the Hulk usually involves helping him with those issues, often meaning not bottling things up so much. Sometimes this results in fewer Hulk episodes, sometimes it results in a smarter Hulk, and at least once it resulted in a Banner with the Hulk's strength.

Films -- Live-Action
""I see pride! I see power! I see a bad ass mother who won't take no crap off of nobody!""
 * The whole point of Anger Management.
 * The Waterboy. Coach Klein told Bobby Boucher he could stand up for himself, and then he remembered all the people that had been mean to him over the years, and that was his "tacklin' fuel."
 * Yul does this to Junior in Cool Runnings.

"Your eyes are full of hate, forty-one. That's good. Hate keeps a man alive. It gives him strength."
 * In the Disney version of The Reluctant Dragon, the boy tries to get the dragon to breathe fire, but can't because he needs to be mad to do so, and he's not mad at anyone. It's only when the boy insults his poetry that the dragon starts spewing flames.
 * In Star Wars Episode III, the Emperor did to Anakin. In Star Wars Episode VI, he tried to do to Luke. (Luke falls for it twice, but the third time he refuses to attack, and is promptly fried by a disappointed Sith Lord.)
 * Star Trek XI. Definitely example #2, as ALL Vulcans possess a violent beast beneath their calm exterior (and they're a lot stronger than humans). So, pushing Spock, who had, while necessary, was very painful for Kirk. Very painful.
 * In Ben Hur, Quintus Arius talks about this.


 * This is the means by which the bad guys seek revenge against Mr. Miyagi by transforming Daniel-san into the opposite of everything Miyagi taught him to be, in Karate Kid III.

Literature

 * Wizard's First Rule has Zedd teach Richard how to channel his anger instead of surpressing it, which allows him to use the full power of the Sword of Truth.
 * Emperor Mage, the third book of The Immortals quartet, Daine learns to use her anger to focus her power, though admittedly she has plenty to be angry about already.
 * Not precisely. Her anger over simply gave her the motivation to seek out a source of power strong enough that she could punish Ozorne with it. Though this does lead to some rather entertaining dialogue when she is talking back to the Hag.
 * In Carpe Jugulum, the Magpyr family are vampires, the patriarch of which has extensively trained to resist all the classic vampire weaknesses because he doesn't see why they have to do it the stupid way and lose some of the time when they can win all the time with training. When the old Count de Magpyr returns, he's encouraged to take his grandchildren under his wing and teach them stupid, because biding your time, dead, for a few decades, is how a vampire really gets ahead.
 * Dialed Up to Eleven in The Fionavar Tapestry trilogy by Guy Gavriel Kay. The race of Giants are the ultimate pacifists, unable to hate and unwilling to defend themselves. All but one refuse to even so much as ask for aid when they are being slowly tortured to death, because it would mean someone else has to battle on their behalf.
 * The Novelization of Revenge of the Sith makes the Sith efforts to do this to Anakin more explicit - Count Dooku thinks that the plan is that he kills Obi-Wan, then Darth Sidious talks Anakin into joining the Sith, then Dooku surrenders and gets to sit out the war and become part of the developing Empire. It doesn't work quite like that.
 * This is Played for Laughs in the Thursday Next novel Something Rotten, where Hamlet himself gets some life-coaching on how to be take action and be more assertive.

Live-Action TV

 * The "bad outcome" of this occurs in an episode of Farscape, "That Old Black Magic." Zhaan must revive her old sadistic anarchist ways in order to defeat Maldis. It takes her several episodes to fully regain her self-control.
 * In one fourth season episode, where an evil spider alien stole the most important aspects of the main cast's personalities (John's determination, Aeryn's self-control, Chiana's sex drive, Rygel's greed, D'argo's anger), Chiana proves it by trying to teach D'argo anger again by beating him up. It doesn't work, which is a really big problem.
 * Star Trek the Original Series has Kirk have to anger up Spock (who's on the feelgood spores) and then let himself get smacked around by an enraged Vulcan until he gets it all out of his system.
 * Doctor Who. One of the Doctor's companions does this to the Thaals, to show them there are some things they're willing to fight over. The Thaals had previously been willing to be exterminated by the Daleks rather than break their pacifist ways.
 * On Thirty Rock, Kenneth of all people takes it upon himself to push new guy Danny Baker to anger so that he doesn't get stepped on by Tracy and Jenna.

Videogames

 * Jade Empire allows an evil character to do this to Dawn Star.
 * Organization XIII attempts to do this in Kingdom Hearts 2 to Sora, I think.
 * It wasn't necessarily that they were trying to teach him anger. Rather, they were trying to exploit his anger and his drive to protect his friends in order to get him to further their goals
 * Part of Xehanort's plan in Birth By Sleep.
 * In Planescape: Torment, the Nameless One can teach an NPC how to get angry. The goal is to get her annoyed enough at her co-workers to gossip about them, though.
 * In Sword of the Stars, the second variant describes the training of Black Swimmers. The Liir are a species of Empaths who are pacifistic as a result, but because they need to defend themselves somehow a special caste of volunteers known as the Black Swimmers keep them safe by teaching themselves how to hate and kill. Black Swimmers are basically irredeemably Ax Crazy by Liir standards and both sides are all too aware of this, but are nonetheless necessary for the race as a whole to survive. Their Initiation Ceremony involves 'drowning' the aspirant in liquid oxygen until they black out and abandon all hope.
 * In Phantasy Star IV, the main character can go to the Anger Tower and learn, arguably, the most powerful technique in the game, which happens to be fueled by anger; this trope comes into play when Re-Faze puts Chaz to a Secret Test of Character: forcing him to confront and then kill a specter of his deceased mentor and surrogate mother, and then taunt him for his pain after realizing it was an illusion, then offer to teach him the Forbidden technique to taunt him with how incredibly powerful it would be.
 * The Beast does this to Will in Days of Ruin in order to make him a satisfying opponent. His method of doing so? Killing civilians. It works well enough that the Beast is never seen again after that mission (presumed dead based on Caulder's lines).

Webcomics

 * Related variation in Casey and Andy, where Jen has to teach Quantum Cop how to lie. This pays off in the Grand Finale.
 * In the "That Which Redeems" arc of Sluggy Freelance, Torg tries this to multiple characters in the Dimension of Lame in order to get them to defend themselves against the demonic invasion. He fails; the people in the Do L are so pacifistic that even a character who would be Axe Crazy in any other dimension can only manage to pound one demon on the foot with a hammer before breaking down into What Have I Done.
 * Gabe in Penny Arcade uses this and Training From Hell to train his Pokémon. He openly states that he trains them to hate, and that translates into victory.
 * In Sinfest, Satan is unable to teach the lesson to Buddha

Web Originals
"Caboose: My name is Michael J. Caboose, and I...HATE...BABIES!"
 * In Red vs. Blue, Caboose (a very nice, but exceptionally dumb member of Blue Team) was possessed by the AI O'Malley. Later, Caboose and Sarge are fighting two armies of flag-worshipping zealots. Caboose claims that "O'Malley taught me how to be mean"; by concentrating on things that make him angry (red bull, kittens with spikes on them), he proceeds to go crazy and wipe out both teams; before waking up with no recollection of his actions.

Western Animation
"Toph: Rock is a stubborn element. If you're going to move it, you've gotta be like a rock yourself."
 * Family Guy does this when Peter decides to train Cleveland after his wife leaves him for Quagmire. It has unfortunates results as Cleveland rampages around Quagmire's house chasing him and revealing beds that pop out whenever he hits something. Hilarity Ensues but Cleveland finally snaps out of it and goes back to being his old self.
 * Oh, yeah, except he's divorced now.
 * He falls in love and gets married again, and it sticks.
 * At one point (deleted scene?) Peter tries to do this to a bunch of stereotypical British kids. His final solution is to show them the American version of The Office.
 * Storm Hawks has Junko pose as a wrestler to get the team into the Cyclonian's enemy base. Since he's normally a Gentle Giant, Piper uses a hypnosis crystal to give him a confidence boost. She then gives it to Finn along with instructions to only use it sparingly, along with the code phrase to turn off the conditioning should an emergency arise. Finn of course uses it so strongly Junko actually believes he is the Masked Masher and can't recognize his friends. It all comes to a head when Master Cyclonis puts them all in a cage match against the Brainwashed and Crazy Junko. Luckily Piper manages to remind Finn of the code phrase.
 * Toph on Avatar: The Last Airbender, due to Personality Powers, has to teach Aang to use the head on, straight forward approach of Earthbending instead of his dodging, nimble approach with Airbending. Her Drill Sergeant Nasty tactics involve grabbing his (bag of) nuts and stealing his staff to make him angry enough to stand up to her.


 * Inverted with... Well, EVERYTHING Uncle Iroh was trying to teach Zuko. Pretty much every other proud Fire Nation warrior used the purely aggressive style of fire bending, meaning Teach Him Anger was more or less class 101 in the academy. Iroh and Jeong Jeong were among the few that realized that was self destructive, not just on a personal level but for the entire nation in the long-term.
 * Accidentally invoked by Megatron on Beast Wars when Scorpinok's mind-altering bug took away Optimus Primal's self-control and inner peace. His reasoning was that Optimus' calm exterior was a facade for a cowardly streak, but in fact it was a safety mechanism to control his Unstoppable Rage. With his peace removed, Optimus goes on a Roaring Rampage of Revenge, taking out the entire Predacon force single-handed before the Maximals manage to remove the bug that was slowly killing him. Beware the Nice Ones indeed.
 * Plankton attempts to invoke this on Spongebob SquarePants as part of a Batman Gambit to make Goo Lagoon a site for a new Chum Bucket. Spongebob, in response, decides to be "aggressively nice".
 * My Little Pony Friendship Is Magic: Iron Will, a minotaur self-help guru in the episode "Putting Your Hoof Down", teaches this as a technique of getting one's way. It particularly applies when the student is Fluttershy. It works too well.
