We passed those eyes of buckshot lead;
Till one cried: "Hangman, who is he
For whom you raise the gallows-tree?"
Then a twinkle grew in the buckshot eye,
And he gave us a riddle instead of reply:
"He who serves me best," said he,
"Shall earn the rope on the gallows-tree."
The villain approaches one of the good guys, often having captured them first. The good guy is then offered a deal: if he will help the villain by betraying his comrades, he will be amply rewarded with money, a high-ranking position in the villain's organization, or something else that would be attractive. He accepts the bargain, and keeps his end of it.
Of course, the villain has no intention of honoring his own part of the bargain. One reason is that no Card-Carrying Villain would want to share anything with a stooge who has outlived his usefulness. Another reason is that smart villains never trust a traitor, no matter which side he's working for — after all, they have proven a willfulness to abandon their cause for filthy lucre's sake; who is to say that they won't turn double agent on the villain at the first ripe opportunity?
So, the traitor gets the "reward" of being put to death or being reduced to menial slavery. Not such a pleasant outcome for him, is that? Frequently this is accompanied by a speech of withering contempt for treachery, which demonstrates that the villain is an honorable enemy or Worthy Opponent to some degree — though in most cases this only serves to make the villain look like a great big hypocrite (after all, he did solicit and employ a traitor, and by invoking this trope, betrayed them). In other cases, it could be more Pragmatic Villainy; as noted above, trusting a proven traitor is never a good idea. In a variation, the hero refuses to turn, and is rewarded and praised for his loyalty.
Sometimes it happens in reverse, where the good guys are approached with an offer by a would-be Turn Coat from the enemy, and invoke this trope to show their scorn for treachery — before or without even using him or his information. This can be a prime source of Values Dissonance with works created or set in feudally organized cultures, where loyalty placed much, much higher in the hierarchy of virtues than in modern Western society. In these cases, what seems to the reader like a straight MookFace Turn will instead be met with an ostensibly deserved horrible fate. This might be justified for pragmatic reasons, as shoving a HeelFace Door-Slam is much safer than dealing with a would-be Sixth Ranger Traitor.
One frequent variation has the villain show the good guy that he has his wife, and offers to release her from his prison in exchange for his cooperation. When it comes time to reward the traitor, the villain slyly gives him False Reassurance that she has indeed been "released", and that now it is time for him to join her.
In another variation, the villain is besieging a city or fortress. Someone leaves a side door (a sewer gate is a popular choice) open, and the bad guys storm in. But when the turncoat comes to the villain for his reward, he's promptly killed because that's what any traitor deserves. This usually either signifies that the villain likes to use it as an excuse to satisfy their bloodlust, or show that they have at least some standards about loyalty (which would, again, make him a hypocrite), depending on how it's played. It generally shows, however, how ruthless and treacherous the main villain is.
The one persistent exception to this trope if the reason for being a traitor was to indulge in their malicious urges that would be allowed under the new regime. While Greed, pragmatism, or cowardice won't save you from this trope, for some reason, the Evil Overlord tends to trust people who betray their comrades out of hatred or cynicism.
Also, historically, smarter betrayers have always had two options open to them for avoiding this punishment. The first, if the betrayal was of a ruler, is to seize power as a de facto Klingon Promotion. Since some cultures consider this a legitimate method of succession, the new ruler will not be considered guilty of treason, though he may have to rule by fear to keep the former ruler's supporters from taking their revenge on him. The other method, if the betrayer lacks the ambition or power to seize the throne and hold it, is not to wait for the axe to fall, but get the hell out of Dodge. Notably, the latter method is especially recommended to anyone who has helped another betrayer achieve the former method: the new ruler all too often gets a taste for backstabbing minions as well as superiors, is just as aware of this as his fellow conspirators, and will surely hate to be reminded that he owes his position to them.
Recurring problem for The Starscream, but a Defector from Decadence may face it too. Compare Treachery Is a Special Kind of Evil. Often, the metanarrative purpose of this trope is to have Bad Guys Do the Dirty Work by having them finish off a traitor that the audience would want to see punished without dirtying the heroes' hands. Frequently accompanied by Contempt Crossfire.

As a result, they are transported to the Amazon, where wackiness ensues.

- Played with and ultimately averted in the Justice League Unlimited finale. In the aftermath of an Enemy Civil War, Luthor's side has beaten Grodd's and Luthor asks if any of them can give a reason they shouldn't continue following Grodd. Killer Frost, one of Grodd's cabal, steps forward, turns around and immediately freezes all the others on her side. This even unnerves the villains on Luthor's side.
Luthor: Killer Frost... you've got a future. Get rid of the rest.
Frost: You got it.
- In Ben 10: Omniverse has a non-lethal example in the episode "Frogs of War": Argit betrays the rebellion to the Incursean Empire. As soon as he has lured them in the trap, Attea shoots him and has him imprisonned with the others.

When he asks General Tong for his reward, Tong hits him over the head with a mallet, knocking him unconscious. He tries to have the robot drop Ramu in a fire pit to kill him, but Samson appears and saves Ramu from death.
- The TRON: Uprising episode "Isolated" has this with Paige's friends. They alert General Tessler to the fact that two ISOs, Quorra and her friend, passed through and were given medical assistance.

- Dragons: Riders of Berk: Mildew, the local Berk Jerkass, betrays his tribe (his chief's son most specifically) to the Outcasts. The result? He spends his residence with the Outcasts in constant terror of being disposed of by his new Bad Boss and has to repeatedly come up with new plans (that always fail) for attacking his homeland to convince Alvin he has not outlived his usefulness. Once the Outcasts are taken over by Dagur and his Berserker tribe, he's demoted to a servant assigned to feeding/taking care of the trained dragons (the creature he hated enough to prompt his betrayal in the first place).
- Surprisingly averted in Xiaolin Showdown, despite the show's usual Black and White Morality. Wuya, a Card-Carrying Villain in nearly every other respect, actually gives Raimundo plenty of wealth and status after his betrayal, with zero strings attached. This ultimately leads to her downfall.

Shuriki gave Esteban the power he wanted when she took over, but not before killing Elena's parents, trying to do the same to Elena herself, and having Victor and his entire family banished from the kingdom, ensuring that at every waking moment, Esteban would be tormented by the guilt of losing everyone he ever cared for.
- Averted in the backstory of Storm Hawks. The Dark Ace of Cyclonia was a member of the original Storm Hawks who betrayed his team when they fought against the Empire for glory and power, and the previous Master Cyclonis followed through on the deal with no strings attached. He even became The Dragon for the current Master Cyclonis in her campaign to conquer Atmos.
