On Friday, February 27th, I’ll be joining a panel at Left Coast Crime with Harriet Cannon, Craig Clevenger, and David Putnam, moderated by Laurie Stevens. Our topic-- “Getting Inside the Criminal Mind”--sounds like fun. If you’re going to write crime fiction, you’ve got to have that motive. So, in preparation for the discussion, I began listing the forces that might drive a person to break the law.
The most obvious motivations are greed, jealousy, rage, hubris, and desperation. There are more, like revenge and compulsion, but for this blog, I’m just going to talk about the five I listed.
Greed and jealousy are siblings. Both come from desire--specifically, the desire for what someone else possesses. It might be money, a car, status, fame, professional recognition, or a romantic partner. Greed whines, “I want more.” Jealousy growls, “I want what you have.” In either case, the criminal act becomes a shortcut, a way to acquire something unattainable--or perceived as unattainable--through legitimate means. Many white-collar crimes, embezzlements, and even murders for inheritance are a result of greed. Many “crimes of passion” are rooted in jealousy.
Rage, on the other hand, often erupts without careful planning. It simmers beneath the surface until one provocation too many causes it to boil over. A barroom insult, a heated argument, a moment of humiliation, or even being cut off on the highway can ignite it. Crimes of rage are frequently impulsive. They are not the product of elaborate schemes but of emotional explosions. In such cases, the perpetrator may not have intended to commit a crime when the day began. The act is born in a flash of anger—and the consequences last far longer.
Hubris is another powerful motivator. This is the belief that one is smarter than everyone else, immune to consequences, or entitled to bend the rules. Some criminals are driven less by need than by arrogance. They believe they can outwit the system, manipulate the evidence, or charm their way out of suspicion. For others, the appeal lies in the thrill itself—the adrenaline rush of taking risks and defying authority. Hubris whispers, “You won’t get caught.” For some, that challenge is irresistible.
Desperation sets the stage for a more complicated moral landscape. When options begin to disappear and survival feels at stake, people may justify actions they would otherwise condemn. If your family is starving and you have no money, would you steal food to keep them alive? Many crimes arise not from ambition or arrogance but from fear and scarcity. Desperation narrows perspective. It transforms illegal acts into perceived necessities.
Of course, human motivation is rarely singular. Greed can mingle with hubris. Rage can be fueled by jealousy. Desperation can coexist with resentment. Real-life crimes—and the most compelling fictional ones—often stem from a volatile mixture of emotions and circumstances.
Mix in a few additives like drug use or revenge and you can have a deadly cocktail of motives.
And then there is the uncomfortable reality that some individuals act without empathy or remorse. While I am not a psychologist, it’s clear that certain offenders display traits associated with sociopathy or an absence of moral restraint. Whether we label that “evil” or understand it through clinical terms, it reminds us that not every crime fits neatly into a rational framework.
Getting inside the criminal mind means recognizing that, at its core, crime begins with motive. And motive, however dark, is almost always human. And interestingly, often, when a criminal acts, they don’t necessarily see it as a bad thing but more as an imperative. Something that needs to be done.
