What Do You Say to a Young Person Who Admires the Unabomber?

I published a novel about the Unabomber this year, and during a book tour stop in Seattle, a high school teacher raised his hand and asked me what he could tell his students about Ted Kaczynski, because he was a hero to so many of them. The question stopped me cold, reminding me that Mr. Kaczynski’s influence is deeper and more widespread than most people realize.

The same feeling of cold unease returned this week when I read news reports that Luigi Mangione, the suspect charged in the killing of UnitedHealthcare’s chief executive, Brian Thompson, had posted a favorable review of the Unabomber’s manifesto online. The similarities didn’t end there. The meticulous planning and use of symbolism in the crime reminded me of Mr. Kaczynski, who spent years choosing his targets, designing disguises (even gluing false soles to the bottoms of his shoes) and leaving messages for investigators. The words “deny,” “defend” and “depose” written on the bullet casings found by Mr. Thompson’s body were an eerie echo of the “FC” for Freedom Club that Mr. Kaczynski carved into his bombs. The fact that Mr. Mangione allegedly made his own gun and carried a copy of his own manifesto reinforced the similarities.

There is, of course, still much we don’t know about Mr. Mangione: a full picture of who he is, and what factors shaped him and motivated him. But the teacher’s suggestion that the Unabomber was a hero to some of his students pointed to a larger truth. To many young people living in a system of extreme economic disparity, in a world they believe is on the verge of ecological collapse, the Unabomber represents a dark, growing ideological desperation. To them, his ruthlessly intellectualized turn to violence can seem justified.

But what is lost in this lionization of one of the most notorious terrorists in American history is that for Mr. Kaczynski, the desire to kill came first, and the ideological justifications followed. Lonely rage defined him, and he spent far more time tormenting his neighbors than he did on his grandiose plans to bring down industrial society. He killed dogs for their barking, strung razor wire across dirt bike paths and fantasized about murdering a neighboring toddler. The manifesto and its carefully constructed veneer of Luddite and anarchist philosophies were a con to lure others into his world of despair and hatred.

Watching video of Mr. Mangione’s detention, and listening to the words he shouted to the media, I felt a profound sadness. I saw a young man with a promising start in life lost in naïve convictions, and poisoned by his newly formed and corrupt ideology.

Violent men have always gained followers, but Mr. Kaczynski’s continued influence is mostly intellectual. He had a showman’s instinct for manipulating the crowd, and intuited that the advance of technology and collapse of the environment would be the two dominant crises of the 21st century. He callously identified the environmental movement as being the most socially acceptable justification for his crimes, even though he privately denigrated environmentalists in his journals, and proudly littered, poached and illegally logged on national forest land around his cabin.
