When two or more people team up to achieve a goal, it's generally assumed that their goals are reasonably similar. At the very least, what one of them wants to achieve shouldn't conflict with what the others want to achieve. Otherwise, why would they team up?
Because they didn't know what their teammates are after.
Maybe someone lied to them, or maybe they just never discussed the plan in enough detail to know their allies' true goals. Then again, they may have started with the same general goal and one (or more) of the teammates has slipped in their ethical standards and is willing to cross any lines to achieve it. In any case, it's only when their long, elaborate plan is nearing completion that they finally discover what they've been working toward all this time (and how they mean to finally get it). Their reaction is inevitably, "Whoa, I didn't sign on for that!"
Compare Mistreatment-Induced Betrayal and Right Hand vs. Left Hand. May lead to an Enemy Civil War. Even Evil Has Standards can be a cause. May overlap with Not in My Contract if specific agreements are invoked in detail to justify breaking off the agreement.

- Harry Potter:
- As revealed in Harry Potter and the Deathly Hallows, Regulus Black pulled a HeelFace Turn when he discovered Voldemort's plans. Subjugating Muggles and mudbloods was fine. Tearing apart one's own soul in a bid for immortality? Not so much. That could also have something to do with Voldemort's treatment of Kreacher.
- In Order of the Phoenix, Sirius mentions that there were a number of Old Name families like his own who initially thought that Voldemort had the right idea, but then quickly changed their minds about him when they saw how far he was willing to go for Pureblood Supremacy.

However, when he discovered that a girl was kidnapped, he attempted to flee, and implies that he's doing so because "saving students was not part of the job description." It's all the more unheroic because it WAS his job as a teacher at Hogwarts to protect the students, especially as the combat specialist.
- The Stormlight Archive: When the Parshendi killed the Alethi king and retreated to the Shattered Plains, the Alethi declared a war of vengeance on them. Countless young men joined up, determined to show the world that the Alethi would not stand for treachery. Unfortunately, due to the nature of the Shattered Plains, the Parshendi had a massive advantage over the Alethi, so the Alethi chose to lay siege rather than performing a suicidal assault. Then they discovered that chasmfiends like to pupate on the Plains, and each chasmfiend has a massive gemheart, enough to pay for an army for months. The Parshendi need them as well to feed their own army, so they skirmish over them. It doesn't take long before the Alethi have forgotten vengeance, and are instead just fighting for money. Since the wartime military oaths mean the soldiers can't legally leave, many desert and become bandits prowling the Unclaimed Hills west of the Shattered Plains.
- The Hearts We Sold: Cora and James argue this when they discover the Daemon is having the heartless troop fight monsters to prevent The End of the World as We Know It, and that there's no guarantee any of them will make it. The Daemon shuts them up by pointing out that, yes, they did sign up for this — though he didn't tell them what they were getting into, he never forced anyone to make a bargain with him, and he made it clear he expected two years of labor out of all of his charges. He also points out that a lot is riding on it, much more than their own personal safety, and that, furthermore, he's paying them all extremely well for their time. Dee concedes that he's not wrong, though she's still as pissed as everyone else that he didn't tell them upfront what the deal was.
- Firefly: In the second episode "The Train Job," the crew of Serenity take a job to steal supplies from a train by vicious crime lord Adelai Niska.

- After the Resonance Cascade in Half-Life, a special forces group of the United States military (the Hazardous Environment Containment Unit) arrives to clean up the situation — not only by stopping the Xen invasion, but by "silencing" all Black Mesa personnel with lethal force in order to keep knowledge of the incident secret. While some of the soldiers are sociopathic and most carry out their orders without complaint, one Marine in "On a Rail" makes it clear killing civilians is not what he signed on for.
- There's more soldiers in Half-Life: Opposing Force who are clearly not happy with what they've been ordered to do.
- In Spyro: Year of the Dragon, the Sorceress and her apprentice Bianca steal dragon eggs and take them to their Forgotten Worlds.

- Kazuhira Miller in Metal Gear Solid: Peace Walker worked with Cipher as a neutral business partner and have Big Boss rejoin the organization with the intention of expanding the Militaires Sans Frontieres.

- This is Elle Cutleaf's reason for helping you against her Blackwold brethren early in the Combe segment of the Race of Man storyline in The Lord of the Rings Online. The Blackwolds were originally petty brigands until their leader Skunkwood made a deal with the forces of Angmar, a greater evil than Elle was willing to have any kind of part of.

- Tychus Findlay, in StarCraft II: Wings of Liberty, protests along these lines when Raynor reveals that they're going to Char to confront Kerrigan. He tries to convince Jim to just take the money and run. As Gabriel Tosh notes if you still have him there, Tychus is trying to avoid doing something he doesn't want to—that "something" later revealed to be that Tychus has been tasked with killing Kerrigan, despite the wishes of his friend. Tychus dies on Char, after attempting to shoot Kerrigan—a situation which may or may not have been a case of Suicide by Cop.
- Tychus also protests quite strongly to facing down an army-strength Tal'darim force on the Xel'naga worldship, backed up by "rip-fields" that tear apart anything that approaches them, with a snarl that he "didn't sign up for no suicide mission".

- Neither Mike Schmidt nor the previous security guard were informed of the homicidal animatronic animals they'd have (no chance) to fend off when they signed up to work Five Nights at Freddy's.
Security Guard's Night 1 Message: Now, concerning your safety: the only real risk to you as the night watchman here, if any, is the fact that these characters... uhh, if they happen to see you after hours probably won't recognize you as a person. They'll-they'll most likely see you as a metal endo-skeleton without its costume on. Now, since that's against the rules at Freddy Fazbear's Pizza, they'll probably try ta... forcefully stuff you inside a Freddy Fazbear suit. Umm, now that wouldn't be so bad if the suits themselves weren't filled with crossbeams, wires and animatronic devices, especially around the facial area, so you can imagine how having your head forced inside one of those could cause a bit of discomfort... and death. Uhh... the only parts of you that would likely see the light of day again would be your eyeballs and teeth that would pop out the front of the mask, heh... Yeah, they don't tell you these things when you sign up...
- Fire Emblem Awakening:

You are a SWAT officer!!"
- In The Simpsons, the founding of Springfield and Shelbyville, as well as the feud between the two towns that followed, is based on this trope.

- Gorilla Grodd assembles a new Legion of Doom, but, aside from opposing the Justice League, keeps their long-term goals largely to himself. When it's revealed that his master plan is to turn everyone on Earth into apes, Lex Luthor shoots him in the chest, takes over the Legion, and redirects their efforts to more sensible endeavors (well, sensible for him, at least).
- Hawkgirl willingly signed on to infiltrate Earth and learn the weaknesses and abilities of the planet's society, military strength and its heroes in order to help the Thanagarians subjugate the planet to build their hyperspace bypass. Once she learns the bypass will destroy the Earth, she defects and helps the League destroy it.
- In the Batman: The Animated Series episode "Joker's Millions", the Joker hires a replacement for Harley, claiming that it's cheaper than buying the real one out of jail. The one he gets isn't nearly as good as the real one, and she says twice that this "wasn't in the job description" (the second time when she's arrested; still, this was the Joker... she should have known better. Still, she can take comfort with the fact that the real Harley did get revenge on the Joker for the insult...)
- King of the Hill had a show where Hank met another dad who was appalled with the way the history of the Alamo was being rewritten in the new history books the school had recently purchased. They both agree to put on a play that showed the history of the Alamo, with Hank building the set and the other guy writing. Turns out Hank's vision was of the traditional heroic picture of the battle he remembered from his childhood and the other guy had written a play depicting all the soldiers as drunks and cowards (not because he thought it was more historically accurate, just for the buzz such a "controversial" depiction would get him and his Hollywood dreams).
- The Captain of the Guard allowed the Viking leader Hakon to invade Castle Wyvern in the premiere of Gargoyles in exchange for what is implied to be allowing Demona and the other Gargoyles to gain control of Castle Wyvern. When Hakon decides after capturing Castle Wyvern to smash the hibernating Gargoyle statues, the Captain of the Guard attempts to stop him, citing that this was not what they agreed to do. Unfortunately, Hakon forces him back and resumes smashing the hibernating Gargoyles, with the Captain of the Guard only being able to watch in horror at what he unwittingly brought about.
- The Legend of Korra:
- In the episode "Turning The Tides", Tenzin has to find members of the council in the city, so he tells his ex-girlfriend Lin Beifong to help his wife Pema around the house. Pema comes out with a dirt-covered Meelo and asks Lin to help her give him a bath, and then Meelo says he has to poop. This makes Lin say this exact quote.
- Mako also says something like this in "Rebirth", when Korra rough-houses with him during an Airbending session.
- Played far more seriously in Book Four, when Bolin comes to the realization that Kuvira's army, which he joined in order to aid the Earth Kingdom, has become a force of conquest that imprisons dissenters in camps.
- In the first episode of Total Drama, Chris gets this reaction from certain campers when they learn that they'll be staying in a cruddy camp instead of the four-star resort they were promised.
Gwen: I did not sign up for this.
Chris: Actually... [holds up contract] you did.
- Averted with Fred from George of the Jungle in the Super Chicken segments. As he says, "I knew the job was dangerous when I took it."
- It is rare, but not unknown, for serving soldiers to desert rather than fight, quoting this very reason for their refusal.
- An example would be Lance-Bombardier Victor Williams of the Royal Artillery, who in 1991 deserted on grounds of conscience rather than fight in Iraq.
- There is also a story of an Irish-born soldier in the Parachute Regiment, who had a crisis of loyalty on a tour of duty in Northern Ireland. In the aftermath of the killings of Bloody Sunday,note this individual is said to have deserted with a rifle and lots of ammunition and defected to the Provisional IRA.
- In the US Military services at least, this is a legal defense for refusing to obey orders, but not quite desertion. There is a condition, however — it's only valid if your commanding officer is ordering you to commit a war crime, and you'd better be able to defend your actions during a court martial
- When George Atzerodt, one of John Wilkes Booth's accomplices, agreed to help him, he thought the plan was only to kidnap Abraham Lincoln (which admittedly had been Booth's original plan). Atzerodt only learned the true plan — to simultaneously assassinate Lincoln, Vice President Andrew Johnson, and the Secretary of State — on the day it was to be carried out. Atzerodt told Booth this wasn't what he'd signed up for, but Booth told him it was too late for him to back out. Instead of attempting to assassinate VP Johnson as he was supposed to, Atzerodt went out and got drunk instead, though he was still arrested and hanged as a co-conspirator.
