Lanterns and Sinestro: the psychology of fear as a method of control

In August 2026 Lanterns lands on HBO Max and brings back a corner of the DC universe that the general public only half knew: that of the Green Lanterns. The series follows Hal Jordan and John Stewart, two cosmic police officers with rings that materialize whatever the will imagines. But out of that same world comes a figure who interests criminology far more than any hero: Sinestro. In his origin he was the best of them all, the model lantern. And precisely because he was, he reached a chilling conclusion: that order is only guaranteed when the governed are afraid. He founded the Sinestro Corps, wielded the yellow ring fueled by terror, and turned his planet into an experiment in perfect obedience. The question he leaves on the table is not the stuff of comics: does fear really produce order?

Before we go on, the house rule: to explain is not to excuse. Dissecting the logic of a fictional tyrant serves to understand a very real political temptation —that of the «iron fist» that promises peace in exchange for terror— not to prove him right. Let us keep that distinction lit, because it is precisely the point where Sinestro's argument falls apart.

// The theoryBeccaria, Bentham and the three legs of deterrence

Deterrence theory was born in the Enlightenment with Cesare Beccaria and his treatise On Crimes and Punishments (1764), and is completed by the utilitarianism of Jeremy Bentham. Its underlying idea is simple: the criminal is a rational being who weighs costs and benefits, so he is deterred when the expected punishment outweighs the loot. Now, Beccaria was explicit about what makes a punishment deter, and it is not what Sinestro believes. Effective punishment rests on three legs: certainty (the probability of being caught), swiftness (how quickly the sanction arrives) and severity (the harshness of the punishment). And Beccaria warned that the certainty of a moderate punishment deters more than the dread of an atrocious but improbable one. Two hundred and sixty years later, that intuition remains the key to the debate.

// The characterSinestro: the yellow ring and perfect obedience

In the emotional spectrum of the power rings, green is willpower and yellow is fear. It is not a decorative detail: it is the entire thesis of Sinestro turned into energy. Convinced that his home planet, Korugar, would only prosper under absolute control, he subjected it to a graveyard peace: no crime, no disorder and no freedom. When the Green Lantern Corps expelled him for tyrannizing those he was meant to protect, he did not renounce his method: he industrialized it. He founded the Sinestro Corps and handed out yellow rings to the beings most capable of inspiring terror in the universe. His promise to every world is always the same: I bring you order; you give me obedience.

What is disturbing about Sinestro is that he is not a lunatic. He is an idealist of order. His argument —that security justifies any degree of coercion— is the same one that real authoritarian regimes have wielded to sell repression as stability. That is why he works as a mirror: he does not frighten us because he is monstrous, but because his reasoning sounds reasonable for one dangerous second. Criminology exists, in large part, to dismantle that second.

// The evidenceWhat modern criminology actually knows

This is where fiction collides with the data. The criminologist Daniel Nagin, in his synthesis «Deterrence in the 21st Century» (2013), reviewed decades of research and reached a conclusion Sinestro would hate: the certainty of being caught deters; the severity of the punishment, barely. Increasing the probability that a crime is discovered and sanctioned reduces crime; lengthening sentences or making them harsher produces small or null effects on those who weigh the risk. The reason is psychological: the potential criminal rarely expects to be caught, so the size of the sentence he fears is almost irrelevant. What does carry weight is the perception of real and effective surveillance.

And there is a second finding that sinks the Sinestro method entirely: disproportionate punishment not only deters worse, but can generate more violence. It is the so-called brutalization effect, documented around capital punishment: the display of state cruelty ends up normalizing violence instead of containing it. To this is added the work of Tom Tyler in Why People Obey the Law (1990): people comply with rules above all when they perceive the authority to be legitimate and to treat people fairly, not when they fear it. A power that only terrorizes manufactures fragile submission, resentment and —in the long run— more disorder than it claims to fight.
