Who Should Build the Railing?

Why prevention deserves as much of our attention as blame after tragedy.

Turn on daytime television for any length of time and the commercials become familiar. Have you been injured in an accident? Were you harmed by a medical procedure? Were you involved in a collision? You may be entitled to compensation. The advertisements differ, but the underlying story is almost always the same. Something has gone wrong. Someone has suffered. Now the task is to determine who is responsible and what that suffering is worth. There is nothing inherently wrong with that.

A society committed to justice needs mechanisms through which people who have genuinely been harmed can seek redress. Negligence is real. Malpractice is real. Corporations, professionals, institutions, and individuals sometimes fail in ways that cause devastating consequences. Without meaningful accountability, the powerful would too easily escape responsibility for the damage they cause.

The Torah knows this. Biblical law devotes considerable attention to damages, restitution, negligence, and responsibility. Judaism has never taught that suffering should simply be accepted or that those who cause harm should automatically be absolved. Still, there is something revealing about how much of our moral and legal imagination begins only after the accident has already happened. Who was at fault? Who should pay? How much should they pay? Was there negligence? Was someone warned? Could this have been prevented? By the time those questions are being asked in a courtroom, someone has already fallen.

Ki Teitze asks us to move the clock backward. Among the many commandments in this extraordinarily dense Torah portion appears one deceptively simple instruction: “When you build a new house, you shall make a parapet for your roof, so that you do not bring bloodguilt upon your house if anyone should fall from it.” The Torah does not begin with the injured person lying on the ground. It begins with the builder standing on the roof. No one has fallen yet. There is no plaintiff. There is no defendant. There are no damages to calculate, no insurance company to call, no reputation to defend, no family grieving an irreversible loss. There is only a roof, an edge, and the ability to imagine what might happen. Build the railing. That small commandment represents a profound shift in moral perspective.

Our legal system necessarily spends enormous energy looking backward. Once harm has occurred, justice requires us to reconstruct events. What happened? Who knew what? What should someone reasonably have done? Who bears responsibility? The parapet asks many of the same questions, but before the injury. What can I already see? What danger can I reasonably anticipate? What can I do now so that we never have to determine who was at fault? This is not a demand for omniscience.

The Torah does not hold us responsible for every conceivable tragedy. Human beings cannot predict every accident, anticipate every failure, or eliminate every risk. A world without risk would also be a world without freedom, experimentation, growth, or much of what makes human life possible. The roof itself is not forbidden. People may still climb onto it. The Torah does not say, “Someone could fall, therefore abolish the roof.” It says: recognize the danger that is reasonably foreseeable and do what you can to reduce it. That distinction matters. There is an enormous moral difference between something that could not have been known and something we saw but chose not to address. The category is foreseeability. Modern law knows that word well. But Ki Teitze turns foreseeability from a courtroom argument into a spiritual discipline. It asks us to cultivate the ability to notice danger while there is still time to do something about it.

That may be where the Torah offers an important critique of a culture increasingly accustomed to thinking about responsibility through the language of blame and compensation. Again, the problem is not that people seek compensation. Sometimes compensation is precisely what justice requires. The problem begins when compensation becomes our primary moral vocabulary for suffering. Something terrible happens, and almost immediately we search for someone to blame. Sometimes there is someone to blame. Sometimes there was recklessness, dishonesty, indifference, or gross negligence. But not every tragedy has a villain.

Human beings make mistakes. Physicians sometimes make careful judgments that lead to terrible outcomes. Drivers make momentary errors. Machines fail. People miscalculate. Accidents happen even when reasonable precautions have been taken. A mature moral system has to preserve distinctions between deliberate harm, recklessness, negligence, error, and genuine accident. The Torah certainly does.

Elsewhere, biblical law distinguishes the murderer from the person who causes death unintentionally. The institution of the cities of refuge emerges from precisely that moral complexity. A death has occurred. The loss is real. The grief is real. Yet Torah refuses to pretend that every person who causes a death is therefore a murderer.

Consequences matter. So does intention. So does negligence. So does the difference between what could and could not reasonably have been foreseen. When those distinctions collapse, accountability can become retribution. And retribution carries consequences of its own.

A lawsuit may provide legitimate compensation to one person while destroying the reputation of another. Fear of litigation can encourage institutions and professionals to practice defensively, sometimes directing attention and resources toward avoiding liability rather than toward serving people well. A search for someone to punish can give grieving families the understandable hope that assigning blame will somehow restore what has been lost. Sometimes accountability brings justice. Sometimes it simply produces another damaged life.

The Torah’s parapet offers a different starting point. Before asking how suffering should be compensated, ask how suffering might be prevented. Before asking who deserves blame, ask who has the capacity to act. Before calculating the cost of the fall, build the railing. This is not merely a legal principle. It is an approach to human relationships. A marriage begins to show signs of strain. We can wait until resentment hardens and then spend years deciding who failed whom. Or we can notice the edge of the roof while there is still time for a conversation. Someone in a family becomes increasingly isolated. We can explain afterward why nobody understood how much that person was struggling. Or someone can make the call now. An organization discovers a weakness in one of its procedures. It can decide that changing it is inconvenient and wait until the weakness produces a crisis. Or it can build the railing. A society learns that a technology carries foreseeable risks. It can wait for catastrophe and then search for defendants. Or it can ask what guardrails belong in place before the technology becomes impossible to contain. In each case, the parapet represents the same moral movement. Responsibility begins before blame.

That may be the deepest contrast. Blame is retrospective. It looks backward and asks, “Who caused this?” Responsibility can be prospective. It looks ahead and asks, “What is mine to do now?” We need both questions. After genuine wrongdoing, justice demands accountability. After injury, people may deserve compensation. After negligence, institutions may need to change. But a society obsessed with the first question and insufficiently practiced in the second will become exceptionally good at explaining disasters it failed to prevent.

Ki Teitze imagines something better. The most morally successful railing will never appear in a courtroom exhibit. No attorney will hold it up before a jury. No insurance company will calculate the value of the injury it prevented. No newspaper will report the tragedy that did not happen. No family will know the grief it was spared. Nothing happens. That is its achievement. And this may require us to rethink what moral success looks like.

We notice heroism because something dramatic has happened. Someone rushes into danger. Someone rescues a stranger. Someone repairs terrible damage. We are less likely to notice the person who quietly saw the danger first and removed it. The parent who made the call. The physician who ordered one more test. The administrator who changed the procedure. The friend who refused to ignore the silence. The engineer who insisted on the safeguard. The neighbor who fixed the loose step. No catastrophe followed. There was no story to tell. The railing held.

Most of us will not find ourselves in a courtroom tomorrow morning. We will find ourselves in homes, offices, schools, synagogues, hospitals, businesses, and ordinary relationships. And somewhere in that ordinary day, we may notice an edge. Something that is not yet a crisis. Something we could easily walk past. Something for which no one can blame us because nothing has happened yet. That is precisely the moment Ki Teitze wants us to notice.

Our culture has become very good at asking, after someone falls, “Who should pay?” Torah asks an earlier question. “Who should build the railing?” The answer, uncomfortable as it sometimes is, may be: Whoever sees the edge while there is still time to do something about it.
