openVillain secretly doesn't share henchmen's values Literature
A villain leads a group of Mooks or even leads a country/army. He claims to believe the same ideology his underlings do, which might be something justified (for instance, if they want revenge, he might be presenting himself as an Anti-Villain), or it might be something where they're in the wrong, like some form of Fantastic Racism.
But, in secret, the villain reveals to the hero (in a Bond Villain Stupidity monologue) that he doesn't really believe that crap, and he's only in it for the power and wealth that comes with being the leader. Meaning, he's either masquerading as an Anti-Villain, or actually a Politically Correct Villain who's taking advantage of his underlings' prejudices so he can manipulate them.
He's not a Villain with Good Publicity because he's still considered evil, just a different type of evil than he actually is.
Then, the monologue goes something like, "Of course, I'm not racist. But, by convincing those morons they're the superior race, and my enemies are a threat to their bloodlines, they'll do whatever I want..." and so on.
Of course, he's still a bad guy who's fine with letting his mooks' victims die if he can profit from them in the end, even if he doesn't personally hate the victims.
openObvious change in text to protect reputation Literature
In the Book of Judges, it says (in the original Hebrew) that the grandson of Moses (משה) became a priest for an idol. In order to protect Moses's reputation, there is a "fix" in his name to Menashe (מנשה), but the added letter is written above the main line, making it clearly an addition.
openKill people who are like one's hated parent Literature
A person would like to get his revenge on one of his parents, but the parent in question is dead. So the person murders individuals who, in his opinion, are similar to the parent.
- In Diagnosis: Murder book The Silent Partner, one particular Serial Killer—who had been abused by his mother, had been murdering women.
- In Peter Decker/Rina Lazarus book "Day of Atonement", the murderer killed several big fat men, in revenge for his father abandoning him.

Is there a trope where a story focuses solely on a story arc for a dozen of chapters, while other story arcs are on hold?
