The Lesser Evil Is Still Evil: A refutation of the most dangerous sentence in politics

Short Version

There is a sentence that presents itself as moral clarity but functions, in politics, as moral abdication: the lesser evil is still evil. 

In the abstract, it is unobjectionable. No wrong becomes right by comparison. One can hear in it the authority of Kant —the insistence that moral categories do not bend to convenience.

But the sentence is typically offered not as a description but a conclusion: because both options are flawed, one need not choose. And that is where the sentence changes its nature. What began as a claim about judgment becomes a rationale for withdrawal.

Politics does not ask us to classify isolated actions. It asks us to act among live alternatives that we did not choose and whose consequences will unfold whether we participate or not. To treat all flawed options as morally equivalent is to erase the very distinctions that make political responsibility possible.

The difference between a worse and a less bad outcome is not philosophically trivial; it is the substance of the choice. When that difference is denied, the decision does not disappear. It is just abandoned. And abandonment is not neutral. It alters the outcome in ways that are entirely foreseeable.

The sentence therefore achieves the opposite of what it promises. It preserves the speaker’s sense of moral purity by relocating the consequences of inaction onto others. It refuses complicity while permitting harm. But in a domain where outcomes cannot be avoided, refusing to choose is itself a choice—one that predictably advantages the worse of the available options.

The proper conclusion is not that the lesser evil is good; it is that, in a world of constrained choices, moral responsibility consists in reducing harm where one can, and in refusing the comfort of a principle that dissolves that obligation at the moment it becomes most demanding.

Complete Refutation of "The Lesser Evil Is Still Evil"

There is a sentence that circulates with the authority of moral seriousness: The lesser evil is still evil. In American politics, it is how principled progressives have justified abstention or third-party voting.

The sentence presents as an intellectual full stop. A declaration that one will not be drawn into the the weary arithmetic by which wrongs are compared and then, reluctantly, chosen.

The appeal is obvious. It sounds like integrity.

And yet, in the only context where such a sentence actually matters—where a decision must be made among options not of one’s choosing—it does something stranger. It disables the very capacity it claims to protect.

The sentence is not wrong. It is right, only in a different domain.

In its native habitat—moral reflection—it is almost banal. Of course a lesser wrong does not become right by comparison. No serious ethical tradition denies this. One can hear the echo of Immanuel Kant: the insistence that the moral law does not bend simply because circumstances are inconvenient.

But politics is not the domain in which Kant's idea does its work.

Politics does not present us with isolated actions to be judged against a clean standard. It presents us with choices among live alternatives, each entangled in consequences, each embedded in a world already in motion. The question is not whether an option is good. It is what follows if it is chosen—or if it is not.

This is the point at which the sentence begins to drift.

To say that the lesser evil is still evil is to make a claim about classification. But to use that classification claim as a reason not to choose is to smuggle in a second, much stronger premise: that once a line has been crossed, no further distinctions matter. That wrongs, once admitted, collapse into a single undifferentiated category.

But the entire structure of political judgment depends on the opposite assumption—that differences in outcome, even among bad options, can matter immensely -- they may be morally decisive.

Erase that distinction, and something peculiar happens. One is no longer choosing between a worse and a less bad outcome. One is choosing between participation and withdrawal. The moral drama shifts inward. The question becomes not what will happen, but what will it mean about me if I take part?

It is here that the sentence reveals its secondary function.

It seems to offer a way out.

Not out of politics, exactly—the consequences remain—but out of complicity. One need not decide. One need not be implicated. One may stand apart and say, with a certain dignity, that one has refused to choose evil.

The difficulty is that the world does not distinguish between abstention and absence.

The outcomes proceed. The harms distribute themselves. The difference between what might have been mitigated and what is allowed to occur does not vanish because one declined to engage with it. It simply ceases to feel like one’s responsibility.

But it only feels like that. Washing one's hands of it doesn't actually wash one's hands of it.

In elections, in coalition politics, in movements that fracture at the point of compromise, the language of moral equivalence appears just at the moment when distinctions are most needed. Both sides are bad. There is no real choice. The conclusion follows: disengagement.

But disengagement is not neutral. It alters the field. It changes probabilities. It shifts outcomes in ways that are often entirely predictable.

Which is why the sentence, for all its surface rigor, has a tendency to produce results that are not aligned with the moral intuitions that gave rise to it.

To judge an action as wrong is one thing. To refuse to act when all available options are wrong is another. The first preserves moral clarity. The second risks forfeiting moral agency.

Politics, unfortunately, does not allow us to do both, to retain our moral clarity while abandoning our moral agency.

What it does allow—what it requires—is a more uncomfortable posture. One in which a person may say, without contradiction, that a choice is bad and that it must nevertheless be made. Not because it is good, but because failing to choose would make things worse.

This is not a satisfying position. It offers no purity, no clean lines. It demands that one act in a world that does not conform to one’s standards, and then live with the knowledge that one has done so.

What the original sentence obscures is that the existence of only bad options is itself a moral failure, one that calls not for withdrawal but for repair.

The temptation, then, is to resolve the tension in one direction or the other—to insist either on uncompromised principle or on unembarrassed pragmatism.

Both are evasions.

The first preserves one’s self-conception at the cost of influence. The second preserves influence at the cost of judgment. Neither, on its own, is adequate to the situation politics actually presents.

“The lesser evil is still evil” survives because it seems to refuse that trade-off. It promises clarity without cost.

But there is a cost, one that is borne not by the chooser but the one who suffers the choice.

In the end, the sentence describes the world correctly and navigates it badly. And in politics, that is the more dangerous failure.
