Character craft, examined: flaws (and why they’re often misunderstood)

Writers love talking about flaws.

Give your hero a weakness. A blind spot. Something relatable. Maybe they’re stubborn. Maybe they work too hard. Maybe they “care too much.”

Those aren’t flaws.

Those are personality textures.

A real flaw costs something.

If you want to see what that looks like, watch Daniel Plainview in There Will Be Blood. His flaw isn’t charming. It isn’t redeemable. It isn’t designed to make you like him.

It’s the engine of the entire story.

What a flaw actually is

A flaw isn’t a cosmetic detail.

It’s a trait that drives behavior in ways that create damage. It shapes decisions. It narrows options. It pushes the character toward outcomes that hurt them or others.

Daniel’s flaw isn’t ambition alone. Plenty of characters are ambitious.

It’s his corrosive need to dominate.

He doesn’t just want oil. He doesn’t just want money. He wants to win. He wants to stand above everyone else. He wants to erase competition.

That hunger runs through every scene.

And it never softens.

Why Daniel’s flaw fuels the plot

From the beginning, Daniel presents himself as a self-made man. He tells communities he wants to build schools, roads, opportunity. He speaks the language of partnership.

But underneath that, there’s something colder.

“I have a competition in me.”

He says it plainly.

That line isn’t a confession for growth. It’s a statement of identity.

His need to defeat others drives him to manipulate towns, undercut rivals, exploit landowners. It pushes him into a toxic rivalry with Eli Sunday. It isolates him from his own son.

Every major turn in the story flows from that internal wiring.

That’s the difference between a flaw and a quirk.

A quirk colors scenes.

A flaw creates consequences.

The illusion of vulnerability

Sometimes writers feel pressure to soften a flawed character.

Give them a tender moment. A backstory explanation. A justification that balances the scales.

There Will Be Blood resists that instinct.

Daniel has moments of apparent affection, especially toward H.W. But even those are complicated. The child begins as part of his presentation. A signal of legitimacy. A tool in negotiations.

I’m not entirely sure Daniel even knows when his affection is real and when it’s strategic.

That ambiguity matters.

Because the flaw isn’t interrupted by sentiment. It absorbs it.

When H.W. becomes deaf, Daniel’s frustration bleeds through. The inconvenience outweighs the empathy. Later, when he sends his son away, it isn’t portrayed as a moral crossroads.

It’s another act of preservation. Of control.

The flaw stays intact.

When a flaw becomes destiny

By the final act, Daniel is wealthy beyond measure.

Externally, he has succeeded.

Internally, he has hollowed himself out.

He lives alone in a cavernous mansion. He drinks. He rants. He clings to grudges. His rivalry with Eli resurfaces not because it benefits him financially, but because he cannot tolerate the idea of submission.

The famous bowling alley confrontation isn’t about business.

It’s about humiliation.

Daniel forces Eli to renounce his faith. He mocks him. He degrades him. He escalates until violence becomes inevitable.

Nothing in that scene feels accidental.

It feels like the logical end of a flaw left unchecked.

Why flaws are often misunderstood

There’s a temptation to treat flaws as obstacles to overcome.

Character starts insecure. Learns confidence. Flaw resolved.

But some stories aren’t about correction.

They’re about exposure.

Daniel doesn’t conquer his flaw. He feeds it. It delivers wealth, then isolation, then madness. The story isn’t asking whether he can improve. It’s asking what happens when dominance becomes the only lens through which a man sees the world.

I’ve found that the most compelling characters aren’t those with tidy weaknesses. They’re the ones whose flaws are structural. Embedded. Inseparable from their strength.

Daniel’s drive builds an empire.

It also destroys every human connection he has.

That tension is the story.

What this reveals about character craft

A flaw should complicate success. It should create friction between what a character wants and what they need. It should distort relationships. It should force hard choices. If you can remove the flaw and the plot still functions, it wasn’t doing enough.

In There Will Be Blood, remove Daniel’s hunger for dominance and the story collapses. The rivalry fades. The isolation evaporates. The ending loses its inevitability.

His flaw isn’t an accessory.

It’s the fuel.

And by the time he says, “I’m finished,” it doesn’t feel like victory. It feels like the sound of a man who won everything and lost himself in the process.
