Luigi Mangione why did he do it is the question dominating public attention after the shocking killing of UnitedHealthcare CEO Brian Thompson in Manhattan. While terrorism-related charges have recently been dismissed in state court, prosecutors have laid out a chilling picture of Mangione’s motives, revealing a mix of personal frustrations, anger toward the healthcare system, and a desire to send a symbolic message.

The Incident That Sparked the Question
On December 4, 2024, UnitedHealthcare CEO Brian Thompson was fatally shot outside a hotel in New York City as he arrived for a corporate event. Prosecutors allege that 27-year-old Luigi Mangione carried out the ambush, fleeing the scene before being arrested several days later in Pennsylvania.
The murder stunned corporate America, not only because of Thompson’s high-profile role but because investigators quickly uncovered evidence suggesting the act was planned as a form of protest against the healthcare industry.
What Prosecutors Discovered About Motive
As investigators pieced together Mangione’s actions, several details emerged that helped answer the central question: why did he do it?
- A Manifesto-Like Notebook: Authorities found a red notebook in Mangione’s possession that contained writings describing his grievances against the healthcare system. In it, he spoke of insurance companies as “parasitic” and described corporate executives as symbols of greed.
- Surveillance and Planning: Prosecutors said Mangione had surveilled the hotel where Thompson was staying the night before the attack. This indicated premeditation rather than a spontaneous act.
- Personal Health Struggles: Records show that Mangione suffered a serious back injury in 2023. He wrote about chronic pain, frustration with medical care, and struggles navigating insurance and healthcare bills. These personal issues appeared to fuel his anger.
- Symbolic Targeting: Mangione had no personal connection to Thompson. Instead, Thompson was targeted as a symbol — the head of the nation’s largest health insurer.
Why the Terrorism Charges Were Dropped
Originally, New York prosecutors charged Mangione under state terrorism laws, claiming that his act was intended to intimidate the public. However, on September 16, 2025, a New York judge dismissed the terrorism charges.
The court ruled that while Mangione’s anger and ideological beliefs were clear, there was insufficient evidence that he intended to coerce or intimidate a broader population. Instead, the act was directed at one individual, even if symbolically tied to a larger system.
The Charges That Still Remain
Despite the dismissal of terrorism charges, Mangione continues to face very serious legal jeopardy:
- State Charges: He is still charged with second-degree murder and weapons possession in New York. These charges alone carry a sentence of 25 years to life.
- Federal Charges: At the federal level, he faces charges that could result in the death penalty, including murder with a firearm and stalking resulting in death. Federal prosecutors have already announced their intent to seek the harshest penalty available.
Breaking Down the Motive: Why Did He Do It?
When looking closely at the evidence, the reasons behind Mangione’s alleged actions can be divided into three major categories.
1. Personal Health Struggles
Mangione reportedly endured chronic pain following a serious back injury. He underwent medical treatment but was dissatisfied with the care he received and appeared angry over the costs and insurance disputes that followed.
These experiences may have left him feeling mistreated and ignored by the healthcare system, planting the seeds of resentment.
2. Ideological Anger at Healthcare Corporations
In his notebook, Mangione repeatedly criticized health insurance companies, calling them exploitative and harmful to society. UnitedHealthcare, being the nation’s largest insurer, became the symbol of everything he opposed.
To him, Brian Thompson represented the face of corporate healthcare. The choice of target was not personal but ideological.
3. Desire for Symbolic Impact
Prosecutors say Mangione viewed the killing as a way to make a statement. His writings suggested he believed attacking a high-profile executive would draw attention to issues in the healthcare system.
This combination of personal suffering and broader ideology appears to explain why he acted in such a drastic and violent way.
Public and Legal Reactions
The dismissal of terrorism charges sparked debate:
- Legal Experts praised the court for narrowing the definition of terrorism, ensuring the law is not applied too broadly.
- Healthcare Executives expressed fear and outrage, noting that the attack still clearly targeted the industry.
- Civil Liberties Groups argued that the ruling protected against prosecutorial overreach, while also acknowledging the seriousness of the murder charge that remains.

The Bigger Question About Healthcare Anger
The Mangione case has also reignited debate about public frustration with the U.S. healthcare system. Millions of Americans share anger over rising costs, complex insurance rules, and denied claims. While nearly everyone agrees that violence is never justified, the case underscores how deep these frustrations run.
Looking Ahead
Mangione still faces a long legal battle. The state murder case continues in New York, while the federal government prepares to pursue its own trial that could result in the death penalty. His motives — part personal grievance, part ideology — will remain central to how both cases unfold.
Final Thoughts
The question of Luigi Mangione why did he do it can be answered only by looking at the intersection of personal pain and symbolic protest. While the terrorism charges have been dropped, his writings and actions paint a portrait of a man consumed by anger toward a system he believed had failed him.
As the trials move forward, the case forces the public to confront not just one man’s crime but also the broader frustrations fueling his beliefs. What do you think — was Mangione’s motive more personal or more symbolic? Share your thoughts in the comments below.
