All About Betrayal in Fiction

‘Yet each man kills the thing he loves
By each let this be heard,
Some do it with a bitter look,
Some with a flattering word,
The coward does it with a kiss,
The brave man with a sword!’

b) How To Write About Betrayal In Fiction

Betrayal is the violation of trust and confidence involving deceptive and disloyal behaviour by someone close to you. Betrayal breaks us. It affects us by making us rethink our perception of reality, and our outlook on life. We don’t know who to trust. It makes us second guess every decision, and changes our memories and our sense of self. It is a brilliant tool for writers when they plot their novels. It can be used to change a character or the entire arc of a story.

Tips for Setting Up Powerful Betrayals

1. The Set Up: Set up the betrayal in a way that isn’t obvious, by following the points below.
2. Make Your Reader Care: Readers must be invested in your characters. If the reader doesn’t care about the protagonist or the betrayer, they won’t feel anything when the big deception happens. As a literary device: ‘The protagonist exists as a sympathetic device to drive a story… We need somebody to empathise with in a story – and the protagonist is usually the literary device that facilitates this.’ As a literary device: ‘The antagonist exists to put obstacles in your protagonist’s path. They are there to create conflict. Without conflict, there is no plot… Readers call these characters villains or opposition characters, but they need not be evil or even bad people. If the roles were reversed, the protagonist could become the antagonist.’ As a writer, you can make your readers care about both of them.
3. Build the Bond: Betrayal requires a pre-existing, significant relationship where trust exists. The closer the characters are, the more the betrayal hurts. These characters must spend time together, building memories, and forming bonds. The hero must rely on the betrayer for something important like love, acceptance, or friendship.
4. Choose The Best Betrayer: Pick one of your protagonist’s friends or love interests. What are the worst betrayals these characters could perform? Who will have the most impact on the main character? Let them do it – and make it worth it.
5. Establish Motivation: Ensure the betrayer has a compelling reason—fear, desperation, survival, greed, power, revenge, opposing beliefs—rather than acting for no reason. Revenge is the strongest motivation for a betrayer. They want justice, whatever that may be in their eyes. This makes them a formidable enemy.
6. Use Foreshadowing: You can use your characters’ actions and abilities, the setting, motifs, dialogue, tone, weather, viewpoint – including unreliable narrators, sounds, smells, and tastes to foreshadow. Body language is also a good way to show the real character. Great foreshadowing causes the reader to say, ‘I should have realised this would happen.’
7. Use Point Of View (POV) – Tell the story in a viewpoint that makes it impossible for the reader to see what’s happening behind the scenes. Or you can use an unreliable narrator who is in denial and they don’t tell the reader the whole story. In Gone Girl, the unreliable narrator viewpoint leads readers into twists and turns and betrayals they never see coming.
8. Internal & External Conflict: Show the emotional turmoil of both the betrayer and the betrayed, highlighting the intense, personal pain of the event. Show the destruction of relationships. Show the external turmoil by their actions – they may cry, rage, withdraw, leave, or lash out. Betrayal may even lead to murder.
9. The Realisation: Create a shocking moment when the hero realises they have been deceived. Their world has turned upside down. They have been destroyed emotionally and their viewpoint is transformed. It’s often messy and scary. They should be taken by surprise for maximum effect on the reader. Emotions could include shock, rage, sorrow, confusion, and humiliation. They also feel intense anger, helplessness, grief, paranoia, a loss of self-worth, and a loss of trust in others. They want to know why it happened.
10. The New Normal: The world has changed forever. The character must find a way to deal with what has happened. This will set the story on a new trajectory, create more conflict, and motivate them to realising their story goal.

Types Of Betrayers

1. The Remorseless/Narcissistic Betrayer: This entity acts with no remorse or regret, and they are entitled and lack empathy. (See The Girlfriend by Michelle Frances below.)
2. The Double Agent: This character appears loyal, kind, and trustworthy, often functioning as a close ally of the protagonist. They are masters of deception. They are the trusted companion who is actually the antagonist, or who has been planted by the antagonist. This shatters the betrayed character. To complicate things, the betrayer may have developed genuine feelings for the protagonist, making the final betrayal painful for both of them. (See The Spy Who Came in from the Cold by John le Carré below.)
3. The Jealous Friend: This character betrays out of jealousy, envy, or insecurity. They feel inferior to the protagonist and bring them down to satisfy their own ego. They resent being constantly in the shadow of the hero. (See The Count of Monte Cristo by Alexandre Dumas below.)
4. The Noble Traitor: A guardian figure (holding a high position of trust) sacrifices their honour, reputation, and sometimes their sanity, by betraying a government, kingdom, or person to prevent a greater evil. They see themselves as a necessary evil.
5. The Reluctant Betrayer: A character turns on the hero, not out of animosity, but because the antagonist threatens to kill their family or destroy their livelihood. This forces the betrayal and leaves them guilt-ridden and emotionally damaged. (See Casino Royale by Ian Fleming below.)
6. The False Prophecy: The hero acts on a holy prophecy, only to realise their mentors or leaders have used them as a pawn to win power.
7. The Self-Betrayer: This character betrays their own morals, values, and safety. This type of betrayal often stems from fear of disapproval and a longing for acceptance. (See The Remains of the Day by Kazuo Ishiguro below.)
8. The Accidental Assassin: Two characters fall in love or become close allies. They are unaware, or may be unaware, they stand for opposing sides of a conflict. Authority figures on both sides force them to kill each other, turning the relationship into a fight for survival. (See Mr. & Mrs. Smith or Killing Eve.)
9. The Emotional or Physical Cheater: They share intimate thoughts and feelings with someone else or engage in physical intimacy with someone else. (See Medea by Euripides below.)
