Corruption of a Minor

""You call it 'brainwashing'. I call it 'making it a game'.""

- Big Daddy, Kick Ass

In many countries, there is a crime with a name similar to Corruption of a Minor, which is basically an adult teaching a kid things they "shouldn't" know; generally things that could increase the kid's risk of becoming a criminal. Things like bringing the kid along while committing a crime such as shoplifting, for instance, or outright having the kid help in the commission of a crime.

Anime and Manga

 * Mahou Sensei Negima has Evangeline occasionally being The Vamp around ten year old Negi. Such as the time she told him to lick her feet. This resulted in a Megaton Punch from Asuna.
 * Later she starts doing Kiss of the Vampire feedings on him as payment for her training. It's presented pretty much the way you're thinking, and she gets away with it.
 * Then there was the time that Haruna brought Negi to a manga convention, prompting Chisame to have a major Freak-Out when he started to read a Yaoi manga.
 * In general, lots of girls in the class pull stuff like this on him, especially Marshmallow Hell. His ability to be Not Distracted by the Sexy is incredible. Ironically enough, the girls who he's most interested in are the ones that don't try to pull any seduction type stuff.
 * Not that ironic since My Girl Is Not a Slut.
 * In Pokémon Special, Gold invokes a softer version of this trope; he gets the Togepi egg, and gambles and cheats around it, so when it hatches, it naturally follows such behaviors and becomes mischievous.
 * Yayoi from Koe de Oshigoto! does this to her own sister, giving her The Talk and a lecture on eroge so she could become a good eroge seiyuu. To be fair, Yayoi didn't really push her into the profession and Kanna volunteered.
 * Ali Al-Saachez from Mobile Suit Gundam 00 influenced Krugis children (including The Hero) to kill their parents to prove their devotion to god. The truth is he just wanted to turn them into his Child Soldiers.
 * Johan Liebert does this, to little surprise.
 * One of Hayate's skills is spotting forged art—because when he was four, his father used him in an art-selling scam, and taught him to not accidentally give the real stuff to the people they were swindling.
 * In Kite, Akai and Kanie are in the business of turning orphaned young children into ruthless assassins-for-hire.
 * Genma in Ranma ½ taught Ranma things like theft and took him along while stealing stuff. Happosai used the young sickly Miss Hinako to help in his panty thefts.

Comic Books

 * Big-Daddy of Kick-Ass molds his daughter, 11-year old Hit-Girl, into a murderous Badass Normal Laser Guided Tykebomb through Training from Hell. She comes out with a love of butterfly knives, an affinity with swords and expert marksmanship with handguns.
 * Similarly, assassin David Cain attempted to turn his daughter into the perfect killer; not even teaching her how to talk. However, she rebeled after her first murder and fled, ultimately becoming Batgirl.

Film

 * In Léon: The Professional (aka Leon), an assassin befriends a 12-year-old girl, who demands that he teach her how to kill. In the American theatrical release, he gives her some lessons, but she never participates in an actual murder. In the overseas version, she helps kill at least a dozen people, making her instant rehabilitation at the end a little dubious.
 * In Little Miss Sunshine, the parents sneak the dead body of the grandfather out of a hospital because they didn't have time to be burdened with paperwork just then. Both their children, a teenager and a 7-year-old, are involved in the operation. Furthermore, in one of the alternate endings in the DVD version, the family is seen
 * We also can't forget that Olive probably didn't think of that on her own...
 * Her grandfather taught her that one.
 * In Changeling, Sanford Clark is forced by his Serial Killer uncle to help kidnap other young boys, and later on to dispose of the bodies.
 * In An American Crime, Gertrude encourages her children as well as other children in the neighborhood to abuse Sylvia. Because an adult gave them "permission" to burn her with cigarettes and so on, they get into it pretty quick.
 * Hanna, from the movie of the same name, has been trained by her father to avenge her mother pretty much since her birth. It helps that she's a.

Literature

 * In the Han Solo Trilogy, Han and Lando run into Bria Tharen (an old girlfriend of Han's, whom he doesn't really recognize) and Winter Celchu (an aide to Princess Leia), who at the time is around sixteen. Lando points them out, and Han notes that the one doesn't seem friendly, and the other would probably get you in trouble for Corruption of a Minor (which might seem to mean something more like pedophilia), but given this is the repressive Empire...). Oddly, Winter is about the same age as Leia, whom Han would marry later in life.
 * A more solid Star Wars example is Darth Bane, who takes on Darth Zannah as his apprentice when the latter is about ten.
 * And he didn't need any cookies to do it.
 * In an early mystery novel by Ellery Queen, the entire mystery is
 * Subverted in To Kill a Mockingbird. When Dill is crying during Tom's trial, he and Scout go outside and talk to Dolphus Raymond, the town's alcoholic. To help Dill stop crying, he offers him a drink out of his paper sack. Scout tries to warn Dill against it, but it turns out
 * Oliver Twist.
 * In Maximum Ride, Jeb teaches the flock how to do illegal things like hot wire a car. Justified/Subverted in that they needed to know that stuff to survive.
 * Fancy Zing from I Have A Bed Made Of Buttermilk Pancakes commits the unintentional variety with her daughter Cassie. Cassie knows that her mother writes erotic fiction (without reading the examples we get to see), and can spell words like "fuck" and "cunt". She's also extraordinarily perceptive. So when she submits her entry for the school play, she writes a story where two teachers get their students to teach the class while they have sex. She also includes the two aforementioned swear words, without realising that they're unacceptable in school. And she's also seven.
 * The whole in Harry Potter and the Chamber of Secrets might sort of count as this.
 * becomes a Death Eater at 16. Voldemort encourages to murder and torture people. You know, subtle encouragement like
 * And of course, Voldemort recruited Death Eaters straight out of school the first time round as a matter of course.

Western Animation

 * Then there's stuff like both Brock and Molotov teaching Hank and Dean how to kill people in The Venture Brothers. And that isn't even getting into the time Jonas, Sr. made Rusty kill a man with a house key when he was 9.
 * Ignignot and Err teach Meatwad to smoke, drink and peruse pornography in Aqua Teen Hunger Force (in part by hitting him with the Foreigner belt's "Dirty White Boy" setting). Meatwad may or may not actually be underage, but he's certainly childish.

Real Life

 * "Corruption of the youth" was the famous charge brought against Socrates that led to his execution. In this case, it may have, in part, meant something more like "making adults look stupid in front of the youth".
 * The (late) senior member of the "Beltway Sniper" serial killer duo was convicted of multiple murders, and Corruption of a Minor because his fellow killer was 17 at the time of the murders.
 * Joseph Kony, head of the Lord's Resistance Army, ordered children to be kidnapped to serve as soldiers for him. The documentary Invisible Children shows exactly what they went through.
