Not What I Signed on For

"Government cover-ups were not in my job description!" —HECU Marine, Half-Life: Opposing Force

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 now believes kicking dogs is an acceptable means of obtaining 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 Versus Left Hand. May lead to an Enemy Civil War. Even Evil Has Standards can be a cause.

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).
