Let Your Characters Make Bad Decisions

A man stands at a crossroads in a desert, clutching a half-empty canteen. He knows the water is running low, but he decides to take the shortcut through the jagged canyon instead of the long way around the ridge. He thinks he can make it. He’s wrong. By the time the sun hits its peak, he's lost, dehydrated, and staring at a dead end. That mistake—that singular, terrible choice—is exactly what makes his story worth reading.

This post explores why perfection is the enemy of good storytelling and why your characters need to fail. When characters act logically or make only the "right" moves, the plot stagnically stalls. We'll look at how flawed decision-making drives tension, creates character depth, and keeps readers turning pages. If your protagonist is too smart for their own good, your story might be too boring for anyone else.

Why Do Characters Make Bad Decisions?

Characters make bad decisions because their flaws, biases, and intense emotions override their logic. A well-written character isn't a machine; they are a collection of contradictions and impulses. When a character chooses the path of most resistance—or the path that seems easiest in the moment—it reveals who they actually are beneath the surface.

Think about the classic tragedy. If Romeo had just waited an extra hour, or if Juliet had checked the message, the story wouldn't exist. Their impulsiveness is the engine of the plot. If you write a character who always weighs the pros and cons with the precision of a decision theory expert, you're writing a textbook, not a novel. You want a human. Humans are messy. We make mistakes because we're tired, angry, or scared.

The tension comes from the gap between what the character should do and what they actually do. That gap is where the drama lives. If your character is a seasoned detective, maybe they're brilliant at crime scenes, but they can't stop themselves from trusting a shady informant because they're desperate to prove their worth. That's a bad decision, but it's a human one.

When you're in the thick of a first draft, don't worry about making them perfect. In fact, if you find yourself trying to make them too "correct," you're probably stripping away the friction. You might want to check out my previous piece on refining the rough cut to understand why these messy elements are vital early on.

How Do Bad Decisions Drive Plot Tension?

Bad decisions drive tension by creating immediate consequences that the character (and the reader) cannot ignore. A mistake creates a new problem, and a new problem requires a new solution, which leads to further complications. This is the heartbeat of a functioning narrative arc.

If a character makes a mistake, the stakes immediately rise. Let's look at how different types of "bad" choices affect the pacing of a story:

• The Impulse Choice: An emotional reaction that ignores long-term consequences (e.g., a character punching a boss instead of quitting).
• The Ignorance Choice: Making a move based on incomplete or wrong information (e.g., thinking a map is accurate when it's actually a forgery).
• The Fearful Choice: Avoiding a necessary confrontation because of cowardice, which leads to a bigger disaster later.
• The Arrogant Choice: Overestimating one's own abilities (e.g., a climber attempting a peak without proper gear like a Black Diamond harness).

Each of these creates a "domino effect." One wrong turn leads to a broken leg, which leads to a lost supply of food, which leads to a desperate encounter with a predator. Without the initial bad decision, the story stays flat. It stays safe. And safe is rarely a page-turner.

It’s worth noting that the decision shouldn't feel random. It shouldn't be a "glitch" in the writing. It has to be a logical extension of who that person is. If a character is established as being incredibly cautious, a sudden reckless act will feel like a plot hole. But if that caution is actually a mask for a deep-seated fear of being wrong, then a reckless outburst becomes a profound moment of character development.

What Is the Difference Between a Character Flaw and a Plot Device?

A character flaw is an internal trait, while a plot device is an external tool used to move the story forward. A flaw is a part of the person; a device is a thing that happens to them. The best stories blur these lines by making the character's internal flaws the very reason the plot devices exist.

To help clarify this, I've put together a comparison of how these two elements function in a narrative:

If you rely too heavily on plot devices—like a sudden thunderstorm or a lost key—to move your story, it feels cheap. It feels like you're cheating. However, if the character's inability to keep a key safe (the flaw) causes the door to be unlocked when the antagonist arrives (the plot device), you've created a cohesive piece of art. The external event is a direct consequence of the internal failure.

This is where you can really lean into your world-building. If your setting is a high-tech cyberpunk city, perhaps a character's reliance on outdated tech (a flaw of being stuck in the past) causes a critical failure during a chase. It's not just a random gadget breaking; it's a reflection of their identity.

If you find yourself struggling to connect these dots, you might find it helpful to look at how to give your setting a soul. A vivid, reactive world can act as the perfect stage for a character's poor choices to play out.

The most compelling characters aren't the ones who win despite their mistakes, but the ones who are fundamentally changed by them. A character who makes a bad choice, suffers the consequences, and then learns (or fails to learn) is infinitely more interesting than a hero who simply follows the path of righteousness. Give them the freedom to stumble. It's the only way they'll ever truly stand up.
