Crush. Kill. Destroy!! when turned to Evil. Some especially evil robots have Bad / Worse for their dials, or other stranger settings. Usually a built in form of brainwashing/Face-Heel Turn that means robot A.I. Is a Crapshoot. Any robot with a Morality Dial will always, always have it flipped to the other setting at some point. See also Second Law My Ass, Inventional Wisdom and Mirror Morality Machine. Compare Restraining Bolt, Morality Chip and Berserk Button.

- Judge Dredd:
- The cyborg "Mean Machine" Angel has a dial on his head that controls his personality. The lowest setting is "Surly". Unfortunately for him and everyone around him, the dial is completely mechanical and thus is highly vulnerable to getting stuck, resulting in Unstoppable Rage. It was later removed, returning Mean to his original kind and sensitive personality, and released him to be looked after by his equally gentle son.
- Mean's son also has a dial, but it goes from "Kind" to "Messiah".
- Most robots have it, and rampages are due to a malfunctioning of this.
- In Scud the Disposable Assassin robots have a contempt level which allows you to decide how sadistic your assassin should be. In issue #3, Scud infiltrates a prison in order to kill one of the inmates but is spotted. During the ensuing fight, the warden managed to hit Scud's Contempt Input, hoping to fry his brain. Technically, this worked; a Scud's contempt level usually only goes up to 10. When his input was destroyed, his contempt managed to jump up to 15. Scud then claimed to be "Jesus with a laser gun!" and proceeded to slaughter almost the entire security team. The warden was eventually forced to open the outer doors and pray that Scud would leave of his own accord.
- Solaris, the Living Sun (actually an evil AI surrounded by a star-sized plasma field) in DC One Million was reprogrammed by the Superman of the 505th century with subservience and goodwill. It doesn't stick, though; Solaris never entirely gets the hang of being good, and eventually goes back to being outright evil.
- Tik-Tok's spring in Oz Squad runs his morality rather than just himself. If allowed to wind down, he still functions, but becomes violent and lewd.
Films — Live-Action
- The "Destruction Chip" in Robot.
- Interstellar: TARS and CASE have adjustable settings for humour, honesty and trust. Honesty is usually locked at 90%: they don't think that total honesty is a good idea when communicating with emotional beings. They also have a light on their panels to indicate whenever they are talking in Humor Mode or Sarcasm Mode, but if their humour setting is set sufficiently high they sometimes "forget" to use it as they find the results of having some of their jokes being taken seriously funnier.
- The Doctor on Star Trek: Voyager has a ethical subroutine which can be disabled.
- Before the Doc, came Data. His predecessor/older-brother, Lore, had some bad programming that overrode his ethics in favor of indulging his emotional whims, making him a Robotic Psychopath. There was even a two-parter episode where Lore found a way to feed Data his own negative emotions (mostly just anger) while disabling Data's ethical subroutines, in order to sway his younger brother to join him in a quest to Kill All Humans.
- Wizards of Waverly Place: Wizards vs. Angels story arc had the Moral Compass which made people act according to what the dial was set on.
- In The Sarah Connor Chronicles, reprogrammed Terminators are generally helpful to the Resistance, but in some cases they will "go bad" with no warning and revert to previous Skynet programming to Kill All Humans. Cameron disposes of one such hostile machine, and later on she herself reverts after being hit with a car bomb. After being disabled again and reactivated by John, she overrides her hostile programming, but warns John that doing it was foolish and he should never do it again.
- Doctor Who: In the 2014 episode "Into The Dalek," it's revealed that while the Daleks are born hate-filled, they are actually capable of empathy and caring; It's just that the robot bodies they're contained in are programmed to purge any memories that might teach them such things, effectively keeping them monsters.
- In Calvin And Hobbes, Calvin has one of these installed in his Duplicator, and can create either Good or Bad clones of himself. We've only ever seen the Good duplicate, but seeing as that clone disappeared in a Puff of Logic after having a bad thought, it's probably best that he never made a clone out of pure metaphysical evil later on.
- In The Neverhood, Big Robot Bil must be turned from evil to good by pulling a lever in his chest cavity. In the writings of the Hall of Records, it's theorized that the lever was Bil's creator's clumsy way of giving Bil free will and the ability to choose between good and evil.
- Aperture Science's Turrets have been all outfitted with an Empathy Generator. To keep them able to kill, they also have an Empathy Suppresor.
- Fallout 3's security bots have easily accessible "Combat Inhibitors" which can be hacked or destroyed to disable their Friend or Foe sensors. Hacking the local security terminal similarly lets you set all nearby robots to be inactive, select targets according to Friend or Foe, or Kill Everything.
- The bots in Starship Titanic all have cellpoint settings that determine their personalities, which as a result of the ship's general decay are completely out of whack, rendering most of them too forgetful (Fentible), lazy (Krage), or downright unfriendly (Marsinta) to help the player. Each bot has a sculpture in the Sculpture Room with levers that allow you to reset their cellpoint settings to more helpful levels. This is essential for some puzzles, like getting a class upgrade.
- Sasuke of the Ganbare Goemon series had one, installed by Wiseman for no apparent reason.
- In Barbie: Life in the Dreamhouse, Barbie's robot computer, Closet, has a button that can change it from good to evil.
- All the Light Bots in Bob and George. Bass, though not a Light Bot, has a Stupid/Evil switch.
- The webcomic Rob and Elliot had one of these.
- Curvy, on this page, features Nazi-Bots, each with a little switch on the back of his helmet that can be set to either "Nazism" or "Democracy."
- In Commander Kitty, Zenith is a perfection-obsessed android creature of indeterminate species who would like nothing more than to conquer the galaxy. However, once she's rebooted in "Safe Mode," she returns to her original personality: Fortiscue's friendly, helpful, fashion-conscious lab assistant.
- The Simpsons:
- Treehouse of Horror had an evil Krusty the Clown doll with one. It was revealed that this was why it kept trying to kill Homer. When it was switched to "Good," it became Homer's unwilling servant.
- Bart once set a dozen Roombas from "off" to "malevolent sentience".
(solemnly and sadly) "This isn't a war, it's murder." [flicks switch] (imitating Groucho Marx) "This isn't a war, it's moy-duh."
- And played straight in the "Cops and Robots" episode of The Backyardigans. Turns out that the all robots, including the robotic villains, have a good/bad lever, and somehow the villain robots' lever have been set to the 'bad' position. It also provides for the plot in which the villain plans to infiltrate a robot factory and change the position of the switch of all the robots produced by the factory to 'bad'.
- Kim Possible had an episode where Team Go was all hit by a Morality Ray. The good members turned evil, but Shego had already become a villain, so she turned good.
- Invader Zim: Gir is usually harmless and incredibly stupid, but when locked into "duty mode" by a new remote control, he becomes ruthlessly effective and decides Zim is holding the mission back.
- Time Squad: One episode shows that Larry has an emotional dial. It is accidentally set to "Dramatic" causing him to utter a parody of one of the most famous lines from "Planet of the Apes", in an episode which parodies the story/movie.
