I am far from the only one who sees America's vengeance culture. Here are some others who see it, including academics:

The call for vengeance is rooted in the nation’s very founding, in the way English settlers treated the native people and each other. Over the last four centuries, it has repeatedly been expressed as violence acted upon the most defenseless people, scapegoats of social tyranny. Vengeance is the Achilles heel of what it means to an American, negating the hope that inspires each generation and continues to draw immigrants.

The most gruesome recent examples of social vengeance were the state murders of Troy Anthony Davis in Georgia and Lawrence Russell Brewer in Texas. For many supporters of the death penalty, these killings illustrate the blindness of justice: death was inflicted fairly on an obviously wrongly-convicted black man and an unrepentant racist white man. For anyone who believes in a humane sense of justice, one that has a moral or ethical (as opposed to a vindictive or punitive) lesson at its heart, these acts illustrate how barbarity is accepted as a normal part of American life.

...

From the return of the death penalty to the wars on terror and in Iraq, Americans demand retribution and moral certainty; they assert the "rights of victims" and make pronouncements against "evil." Yet for Aladjem this dangerously authoritarian turn has its origins in the tradition of liberal justice itself - in theories of punishment that justify inflicting pain and in the punitive practices that result. Exploring vengeance as the defining problem of our time, Aladjem returns to the theories of Locke, Hegel and Mill. He engages the ancient Greeks, Nietzsche, Paine and Foucault to challenge liberal assumptions about punishment. He interrogates American law, capital punishment and images of justice in the media.

In this season of gratitude and goodwill, we’re greeted with headlines reporting revenge travel, revenge dressing, revenge impeachments and revenge of presidential proportions in the 2024 campaign of Donald Trump. But are Americans avengers?

The answer was simple once. Yes, we dreamed of revenge, cheered it at theaters and sports arenas, secretly wished it upon bosses and double-crossers. We prayed revenge would right family slights and false friends. Yet we respected the line between fantasy and action. Our society demanded it. Vengeance was considered uncivilized, unethical, an act of ugly self-destruction. We denied the need to get even.

In recent years though, we’ve seen a surge in vindictive behavior. Judges, journalists, politicians and their families have been targeted with violent reprisals. Online encounters trend spiteful, with TikTok and Bumble fighting the spread of revenge porn. Corporate culture plays like a mud-pit production of “Measure for Measure,” starring Elon Musk. And congressional midterms are a grudge match, the next round scheduled for January, according to the headlines: “The GOP captures the House — and is ready for revenge.”

So are you sure it's not you who has the warped perspective? Considering you're suggesting people commit murder to effect change?
