Tit‑for‑Tat: The Efficient Strategy the State Refuses to Use
Junho Jung
“Eye for an eye, tooth for a tooth” is usually dismissed today as barbaric revenge.
Modern legal minds congratulate themselves for having “outgrown” it, replacing direct retaliation with courts, prison terms and carefully staged procedure.
Yet if we strip away this self‑congratulation and look at the logic, a different picture appears.
The old principle of lex talionis and the modern game‑theory strategy of tit‑for‑tat are not irrational outbursts of anger.
They are highly efficient mechanisms of deterrence – precisely the kind of mechanisms that a monopolistic state would rather suppress.
Why “Eye for an Eye” Worked
In its original context, “eye for an eye” did two crucial things:
It set a ceiling on retaliation.
If someone gouges out your eye, you are not allowed to burn down his village.
Violence is capped at proportional harm, preventing escalation into endless feuds.
It created a clear, credible threat.
If you cause a specific loss, you will suffer a matching loss.
The rule is simple enough that everyone can understand the cost of aggression.
In other words, lex talionis was not just about satisfying rage;
it was a technology for stabilizing conflict.
It turned diffuse vengeance into predictable response.
Modern game theory later rediscovered the same logic under a different name: tit‑for‑tat.
Tit‑for‑Tat: An Efficient Strategy, Not a Tantrum
Robert Axelrod’s famous studies showed that tit‑for‑tat is one of the most robust strategies in repeated interactions:
It cooperates first.
No pre‑emptive strike, no paranoid hostility.
It retaliates immediately when betrayed.
No passive tolerance of exploitation.
It forgives once the other side returns to cooperation.
No eternal vendettas.
It is transparent and predictable.
Others quickly learn: “If I defect, I pay. If I cooperate, we both gain.”
This is not irrational fury.
It is a minimal, rational rule for enforcing boundaries:
Do not start trouble.
If you do, you will experience the same trouble back.
In human terms, the emotional experience of this strategy is often called “anger” or “desire for revenge.”
But underneath the emotion lies a clear functional purpose:
Signal to potential aggressors that harm will be answered.
Maintain a balance of fear that discourages unilateral exploitation.
Seen this way, many acts of retaliation are not mere explosions of feeling.
They are attempts – crude or refined – to enforce tit‑for‑tat when other mechanisms have failed.
The Prosecutor in Bad Guys: When the System Fails
The drama Bad Guys gives a raw illustration of what happens when formal law does not satisfy this basic logic of deterrence and symmetry.
A prosecutor loses his wife to a serial killer.
The killer is arrested, tried, and sent to prison.
From the system’s perspective, justice has been served: the offender is isolated, the case is closed.
But when the prosecutor visits the killer in prison, he sees a man who is merely confined, not broken:
“Why is he still alive as if nothing has truly collapsed?
Why do I bear the weight of loss while he keeps his most precious bonds?”
The prosecutor realizes:
The system has imposed a cost, but not a matching cost.
The killer has destroyed a loved one; the system has destroyed his freedom, but left his own loved one untouched.
The structure of pain is asymmetrical: one side loses a wife, the other loses only convenience.
So the prosecutor does something the law forbids:
he kills the killer’s wife.
He does not do this because it is the “polite” thing to do;
he does it because it is the only act that generates the same kind of wound.
From the perspective of tit‑for‑tat, his reasoning is brutally simple:
“You took an innocent life I loved.
Therefore, an innocent life you love will be taken.
Only then do we stand on equal ground.”
The system calls this barbaric.
But the prosecutor’s logic is internally consistent:
Prison is a way of protecting society, not of matching the victim’s loss.
True punishment, in his eyes, requires mirroring the damage, not just relocating the offender.
One may abhor his act, and there are strong ethical reasons to do so.
But one cannot dismiss it as “mere irrational rage” without seeing that it embodies tit‑for‑tat more faithfully than the law does.
Why the State Refuses Tit‑for‑Tat
If tit‑for‑tat is so efficient as a deterrent, why does the modern state refuse to adopt it?
There are at least three reasons.
Monopoly of legitimate harm
The state wants to monopolize serious coercion.
If individuals or small groups practice effective tit‑for‑tat on their own, the state’s role as sole arbiter becomes less necessary.
Calling private retaliation “irrational” or “primitive” is an ideological move to keep all meaningful punishment inside official institutions.
Fear of uncontrolled spirals
The state points to real risks: misunderstandings, over‑reactions, cycles of revenge.
It uses these risks to justify banning direct reciprocity and replacing it with slow, filtered, bureaucratic response.
In doing so, it does not merely prevent spirals; it removes the clearest deterrent signal from everyday life.
Comfortable asymmetry
An asymmetrical structure of pain is often socially convenient.
Victims absorb the deepest wounds; offenders are handled “humanely” to preserve the moral image of the system.
This allows societies to feel civilized while quietly tolerating the fact that the suffering is not balanced.
The net effect is precisely what many victims feel but rarely articulate:
The law prevents them from enforcing tit‑for‑tat
and then fails to produce any equally compelling substitute.
Their grief becomes a permanent, one‑sided tax they pay to keep the system’s conscience clean.
The Intellectual Snobbery of “Only Legal Process Is Rational”
There is a particular class of observers – often well‑educated, well‑integrated into the system – who respond to stories like the prosecutor’s with brittle certainty:
“He is immature.”
“He is unethical.”
“Only legal process is rational. Everything else is barbaric.”
This attitude deserves scrutiny.
It rests on several unexamined assumptions:
That whatever is written into law automatically carries higher rationality than the intuitive logic of tit‑for‑tat.
That the appearance of restraint – due process, decorum, careful language – is equivalent to actual fairness.
That loyalty to the system is more important than understanding the real structure of loss and deterrence.
In practice, this becomes a kind of intellectual snobbery:
It insults the raw, coherent reasoning of those who refuse to accept asymmetrical pain.
It hides behind abstract principles while ignoring the concrete imbalance faced by victims.
It praises a system for being “civilized” even when that system repeatedly fails to prevent or truly punish grave harms.
Such snobbery is not a neutral moral stance.
It is a class position:
The people who most loudly insist that “only legal process is rational” are often those who personally benefit from the system’s stability.
They rarely have to live with loss that was never properly mirrored;
they mostly live with the comfort of knowing that, if harmed, “something official will be done,” whether or not it matches their pain.
From a philosophical standpoint, the question is not:
“Is revenge always good?”
It is:
“On what basis do we declare direct reciprocity inherently irrational,
while granting an automatic presumption of rationality to systems that often fail both deterrence and symmetry?”
Tit‑for‑tat has clear weaknesses.
It can be misapplied; it can spiral when misperception is high.
But dismissing it as childish simply because it is emotionally intense misses the point:
Its core logic – proportional response, credible threat, cooperation conditional on respect – is deeply rational.
The state’s refusal to implement anything like it is not only about ethics; it is about maintaining control over violence, even at the cost of permanent imbalance for victims.
What This Leaves Us With
We do not need to glorify the prosecutor’s choice in Bad Guys to see what his story reveals:
Modern law excels at containing offenders,
but often fails at matching the victim’s wound.Tit‑for‑tat, in its raw form, excels at symmetry and deterrence,
but carries risks of escalation when applied without nuance.
The uncomfortable truth is that:
The state has chosen a path that protects its own monopoly on harm and its moral image,
While quietly sacrificing the emotional and moral equilibrium that true tit‑for‑tat would provide.
To critically examine this is not to advocate random vigilantism.
It is to refuse the lazy slogan that “only what passes through legal channels is rational,”
and to insist that efficiency, deterrence, and fairness be judged by their actual effects, not by the elegance of the paperwork around them.
The real maturity is not in blindly repeating that revenge is barbaric and law is enlightened.
It is in asking, with open eyes:
Who pays the price when an efficient deterrent is removed?
And whose comfort is preserved by calling that removal “progress”?
