Writers spend a lot of time worrying about likability. Is the character too rude? Too selfish? Too reckless? Will readers judge them? The short answer is yes, readers will judge them. Constantly. Enthusiastically. That’s half the fun. Fiction thrives not when characters behave well, but when they lean unapologetically into their worst instincts and make everyone else’s lives harder.
“Bad” in fiction doesn’t mean poorly written. It means morally questionable choices, messy emotions, selfish motivations, and behavior that would make you side-eye someone aggressively in real life. The problem is that many writers try to sand these edges down, afraid that readers won’t connect with characters who are angry, jealous, manipulative, or deeply inconvenient. In reality, those traits are often what make characters feel alive.
Good people making good choices all the time are wonderful dinner guests and terrible protagonists. Conflict doesn’t come from harmony. It comes from friction. It comes from characters who want things they shouldn’t, who refuse to communicate, double down when they should apologize, and choose the short-term emotional win over the long-term sensible outcome. In other words, it comes from leaning into the bad.
Flaws are often treated like accessories rather than engines. A character might be described as “stubborn” or “hot-tempered,” but the story bends itself around those traits so no real damage occurs. That’s not a flaw, that’s a fun fact. If a flaw doesn’t complicate the plot, strain relationships, or cause consequences, it’s just there for decoration. Let the stubborn character refuse help until everything collapses. Let the jealous character sabotage something good because they can’t stand feeling second best. Let the flaw actually do some work.
Leaning into the bad also means allowing characters to be wrong. Spectacularly wrong. Not just mistaken about a detail, but wrong about people, about themselves, about what will make them happy. Characters who are convinced they’re right, and act on that conviction, are infinitely more compelling than characters who already understand the lesson and behave accordingly. Growth only matters if there’s somewhere uncomfortable to grow from.
Villains understand this instinctively. Antagonists rarely apologize for their behavior. They commit. They believe in their choices. They justify them beautifully. This is why readers often find them magnetic. They lean fully into their darkness, while protagonists sometimes hover nervously around the idea of being imperfect. Let your main characters borrow a little of that confidence. They don’t need to be cruel, but they should be convinced. Nothing drains tension faster than a protagonist who constantly doubts every decision and immediately regrets it in neat, emotionally responsible ways.
Leaning into the bad doesn’t mean glorifying harm or excusing awful behavior. It means acknowledging that humans are complicated and that bad choices often make perfect sense to the person making them. People act out of fear, pride, insecurity, and desire all the time. Pretending otherwise doesn’t make a story morally superior, it makes it less believable.
There’s also a certain joy in letting characters behave badly on the page in ways we’d never endorse in real life. Fiction is a safe place to explore the selfish thought, the angry outburst, the terrible decision made at 2 a.m. when emotions are high and logic has left the building. Readers don’t show up for perfect role models. They show up for emotional truth, even when that truth is uncomfortable.
Messy characters also give you better stakes. When a character risks losing everything because of their own actions, not just external forces, the tension feels sharper. Consequences hit harder when they’re earned. Redemption arcs are more satisfying when there’s something real to redeem. Forgiveness means more when it isn’t automatic.
Harnessing their inner dark and twisty voice also frees writers from moral babysitting. You don’t have to punish every flaw immediately or tack on a lesson like an after-school special. Trust your readers. They understand complexity. They can hold conflicting feelings. They can root for someone while acknowledging that person is deeply flawed. In fact, they prefer it.
Some of the most memorable characters in fiction are not admirable people. They’re fascinating people. They lie. They manipulate. They make choices that feel inevitable and disastrous at the same time. They linger in readers’ minds because they feel real, not sanitized.
At its core channeling one’s inner darkness is about honesty. It’s about letting characters act the way people actually act under pressure, rather than the way they’re supposed to. It’s about allowing discomfort, contradiction, and imperfection to exist without rushing to smooth it over.
So let your characters be difficult. Let them fail. Let them hurt each other and themselves. Let them double down when they should back off. Lean into the bad, and trust that the good - the growth, the change, the meaning - will feel that much more earned when it finally arrives.
