History Main / TroublingUnchildlikeBehavior

->''We loved our daughter very much, but she was evil. Made the horses crazy. Killed our puppies. [[ArsonMurderAndJaywalking Hid the remote.]] Really sick shit. My wife took her to the old family farm and drowned her in the well. I felt a simple time-out would have been sufficient.''

Contrast with WiseBeyondTheirYears, which is about positive strangely-adult behavior, and ActingYourIntelectualAge, which is neutral.

* In ''{{Ben 10}}'', Ben meets Kevin 11, an eleven year old boy who gambles and steals things. This is troubling enough, but Ben still thinks Kevin's a cool guy to hang out with...until Kevin is willing to use his energy absorbing powers to crash two subway trains together and take the cash from the wreckage. When Ben points out that "hundreds of people could DIE!", Kevin shrugs and says "Hey; no pain, no gain."

* ''KodomoNoJikan'' is ''made'' of this trope. To expand on that: [[FilleFatale Rin]] is a nine-year-old who appears to have the sex drive of a [[LoveableSexManiac 20-something man]] — she's constantly saying and doing perverse things to attempt to get a rise out of her third-grade teacher.

* In ''Project: ARMS'', there are quite a few children who end up this way, mostly because the Egrigori are very into using them for evil and dangerous experiments. The first ones we see are Al and Jeff Bowen, who attempt to blow up a high school partly for their mission, but moreso because they themselves were teased in school. Al spends the rest of the series methodically working his way through various battles and trying to kill a Keith with a gun at one point. [[spoiler:Also, a flashback shows us that the twins murdered their own parents and killed a bunch of kids at their school with a poisonous gas that they invented to leave no traces]]. Then we get Carol, an adorable little girl who is introduced cheerfully telling Ryo that she has the power to twist and crush things like metal and human bones with her mind and that she very much enjoys the power that comes with doing this. It's implied that she only went through life by having people fear her, and Ryo [[StefordSmiler calls her bluff on her enjoying it]]. Finally, we get [[spoiler:Dark Alice, who is furious at the world for causing her death and is willing to nuke the entire planet to get her revenge.]]

* After adopting [[ArtificialHuman Pinoko]], BlackJack is more than a little disconcerted to discover that the [[YoungerThanTheyLook 10-day-old]] (who insists she's a "virgin maiden" of [[OlderThanTheyLook 18]] and looks about 6) [[PrecociousCrush has developed feelings for him]] -- but what ''really'' scares him is that she already knows what a virgin is

** It shows a five year old getting a tattoo, cutting his teacher's chair with a chainsaw and being stopped by the police after stealing a car. He continuously explains that his mom said he could. It turns out he'd overheard her cry out "Yes! Yes! Yes!" during sex in another room and assumed that she was replying to him.

* In ''{{Firefly}}'', it's revealed that at ten years old Jayne was shooting spaceport varmints for the bounties, and using the money he earned to [[CrossesTheLineTwice bet on gladiator blood sports]] [[ArsonMurderAndJaywalking and buy beer.]]

* Mindy/Hit-Girl of ''Film/{{Kick-Ass}}'' cusses like a sailor (from [[ClusterFBomb random F-Bombs]] to her introductory quote: "Ok you [[CountryMatters cunts]], let's see what you can do now"). [[PeripheryHatedom No small amount of controversy]] resulted from having an eleven-year old actress using such language on screen. Oh, and she's a '''[[LittleMissBadass trained killer]]''' who can drop a room full of other trained killers with just a couple of handguns. Her actress did all of her own stunts including [[http://www.youtube.com/watch?v=ZitQGc2XV8o the Butterfly Knife display]].

* ''KodomoNoJikan'' is ''made'' of this trope. To expand on that: [[FilleFatale Rin]] is a nine-year-old who appears to have the sex drive of a [[LoveableSexManiac 20-something man]] — she's constantly saying and doing perverse things to attempt to get a [[IfYouKnowWhatIMean rise]] out of her third-grade teacher.

* Daine in Tamora Pierce's ''Immortals'' series [[spoiler: hunts down and slaughters the bandits who killed her family]], aged twelve. Justified by her grief and the fact that [[spoiler: her gift was making her think she was a wolf]], but made more unsettling by the fact that, when she does eventually tell her friends about it, most of them simply shrug it off.
** To be fair, this takes place in a world where knighthood training starts at the age of 10 and it's loosely based on medieval times where kids grew up faster. And her friends have gone through some fairly dark stuff themselves...

* The main cast of ''HigurashiNoNakuKoroNi'' are well-known for their (usually) HatePlague induced paranoia and murder sprees, among many other troubling behaviors. The four oldest characters are only sixteen, with the youngest being somewhere between [[VagueAge nine and twelve]].

* In ''SweeneyTodd'', the title character finds Toby easy to bribe with Gin. As Toby tells Mrs. Lovett, they used to give the stuff to kids like him in the workhouse (child labor laws didn't exist way back when) so they could sleep -- though as he mentions, you wouldn't ever want to sleep there, "not with the things that happen in the dark."
** Don't forget the ending, when he [[spoiler:coldly and quietly slits Sweeny's throat.]]
