I Will Punish Your Friend for Your Failure

"So, from now on, when-EVER Private Pyle fucks up, I will not punish him! I will punish all of YOU! And the way I see it ladies, YOU OWE ME FOR ONE JELLY DOUGHNUT!"

- Gunnery Sergeant Hartman, Full Metal Jacket

If you are evil enough, one way to turn someone to your side or motivate him to stay there is to threaten to hurt someone he cares about. This "friend" might indeed be the target's best friend or a love interest; however, if the target is the kind who tries to protect everyone, almost anyone may serve as a hostage.

This trope is a signature tactic of a Bad Boss. It is also a form of Villainous Demotivator. Those who have their friends and loved ones under constant threat should they fail might be driven to greater efforts. However, in the long run this situation can hardly be good for morale or loyalty to the Big Bad. The target may, and likely will, perform a Heel Face Turn should the opportunity present itself (and it will) in a desperate bid to save their family and themselves from their circumstances.

Can be Played for Laughs if the "friend" is someone the hero doesn't like.

Compare Even Mooks Have Loved Ones, where the Big Bad doesn't directly target his underlings' loved ones but merely shows callous disregard for them. If you actually punish his friend for his failure, that's a form of Revenge by Proxy. See also Blofeld Ploy.

In the book, the whipping boy was chosen to start a new life in the castle with the young prince, who was a Royal Pain. This trope is played with, however as.

Web Animation
"Grant: Why do I get hit whenever he says something?! Girem6: Semantics. Hitting the partner of the offender encourages discipline. Grant: Oh... well in that case, those boots make you look fat. [Grant gets hit again] Grant: Why did I get hit that time?! Girem6: Because I blame your friend for that comment."
 * Girem6 in Smashtasm does this a lot to Grant and Gront, as noted in this exchange:

Western Animation

 * Slade uses this tactic in Teen Titans to (temporarily) convert Robin over to his side. He infects the rest of the titans with nano bots and threatens to kill them if Robin doesn't become his apprentice and follow his every order.
 * Though it's never directly stated, it is heavily implied in a few episodes of X-Men: Evolution that the only reason why Colossus is a member of Magneto's Acolytes is because Magneto somehow threatened his family members who are still in Russia.
 * Tirac from the My Little Pony pilot threatened to kill Spike in order to make Scorpan obey him.

Real Life

 * The Nazis often threatened to kill not only those who tried to resist them, but also their entire families if they tried to defect. This included anyone found harbouring Jews in their homes. Erwin Rommel killed himself specifically to avoid this fate after he was found to be complicit in the plot to kill Hitler.
 * It's also the reason that people in show trials confess to imaginary crimes—if they don't, their families will pay the price. The Soviet Union under Joseph Stalin and the "People's Court" of Nazi Germany, among others, were particularly notorious for it.
 * A story making the rounds in the US intelligence community is about some Chinese exchange students in Soviet Russia, involved in a prank gone wrong. They were arrested, and interrogated by the KGB. The interrogation lasted for hours, and the KGB could get nothing. Finally, they contacted the Chinese Embassy for assistance. A Chinese agent walked into the room, said something to the students, and left. Afterward, the students confessed everything, received whatever punishment was due them, and were sent back to China. Later, the KGB agents wanted to know what the Chinese agent had said to get the students to cooperate. A Chinese translator translated as follows:
 * This is often done in Marine Corps basic training. When one person messes up, the instructors prefer to start with just the offender, but if mistakes continue or they want to make a point, then they get the next guy as well or the whole damn platoon. If the instructors actively dislike you and want you out, then they start punishing the whole platoon except you. When the other recruits are your only support, and the instructors make all of them resent you... either you better be exceptionally mentally tough, or you're quitting (yes, you actually can quit, it's just very hard to unless they really don't want you). The Full Metal Jacket example above is a particularly nasty case of this.
 * Conversely, it is extremely easy to quit the officer accession programs during that period- just say the word and you're out. That's the whole point- only those who can endure it mentally can finish the program and earn the right to lead Marines. Plus they can taunt you with the prospect of quitting. In Boot Camp, the staff is just trying to toughen you up. At the Academy, they really are trying to make you quit.
 * In ancient Rome, if a slave killed his or her master, all of that master's slaves would be executed. The idea being that anyone would be willing to risk their own life for freedom, but few would be willing to put the lives of dozens or even hundreds of other slaves at risk.
 * North Korea reportedly has a series of "family camps" where the families of accused political dissidents are imprisoned for being related to the accused.
 * The idea of the whipping boy is that noble children cannot be physically disciplined, so a common-born child would be disciplined in their place, where the hope that this would make the noble child feel guilty.
