CEO shooter Luigi Mangione laid out his motive on Good Reads
I don't think there's going to be a lot of "Why did he do it?" about this one. He left a review of the Unabomber Ted Kaczynski's book.

It's easy to quickly and thoughtless write this off as the manifesto of a lunatic, in order to avoid facing some of the uncomfortable problems it identifies. But it's simply impossible to ignore how prescient many of his predictions about modern society turned out.
He was a violent individual - rightfully imprisoned - who maimed innocent people. While these actions tend to be characterized as those of a crazy luddite, however, they are more accurately seen as those of an extreme political revolutionary.
A take I found online that I think is interesting:
"Had the balls to recognize that peaceful protest has gotten us absolutely nowhere and at the end of the day, he's probably right. Oil barons haven't listened to any environmentalists, but they feared him.
When all other forms of communication fail, violence is necessary to survive. You may not like his methods, but to see things from his perspective, it's not terrorism, it's war and revolution. Fossil fuel companies actively suppress anything that stands in their way and within a generation or two, it will begin costing human lives by greater and greater magnitudes until the earth is just a flaming ball orbiting third from the sun. Peaceful protest is outright ignored, economic protest isn't possible in the current system, so how long until we recognize that violence against those who lead us to such destruction is justified as self-defense.
These companies don't care about you, or your kids, or your grandkids. They have zero qualms about burning down the planet for a buck, so why should we have any qualms about burning them down to survive?
We're animals just like everything else on this planet, except we've forgotten the law of the jungle and bend over for our overlords when any other animal would recognize the threat and fight to the death for their survival. "Violence never solved anything" is a statement uttered by cowards and predators."

…. it’s amazing. The author, Tolkien, was an Oxford don, deeply serious. He was a scholar of languages, specifically those of early Northern Europe. He knew the myths and legends and sagas backward and forward and translated them into modern English.
He was already at work on his creation of languages when he joined the British military in WWI, along with a number of his friends. I think he was the only one who made it back from the gas and the trenches — maybe there was one other.
It was there in that hell that he started creating another world. He spent the rest of his long life writing about Middle Earth — when he could spare the time from research, teaching, and the myriad duties of a university professor. His published works were largely academic — the translations of Beowulf, Chaucer, the Eddas, and so on — but he kept creating Middle Earth. The enormous success of The Hobbit and LOTR surprised him, I think.
I think the battered paperback set I read in the summer of 1965 was the unauthorized first American publication. I had quite a background in F&SF by that time, since it had always been in the house before I could even read. From sheer experience I intuited good writing from bad, and while this didn’t hit me as a blinding revelation the way it did others, when I read the last page I proceeded to read all the appendices because I could not let it go. I have read it a number of times since then — and in what I think of as a peak moment of my motherhood, I read all of it aloud to my 11 y.o. son in lieu of the books reports he wasn’t writing, but could give orally.
In college I met people who were trying to learn Elvish, which I thought was weird. In my family we read F&SF avidly, but the opinion from Mom was that it was escapism and not literature. As it happens, she was wrong.
The further along in my own education I got, the more I realized the depth of knowledge certain authors brought to their fictional worlds. But not every genre or sub-genre fits every reader. I had a fascinating conversation with a cousin and his wife in 2002. He knows about a dozen languages fluently. She is Chinese and a well-known author in China. (A whole bunch of her books are by now translated into English) In any case, LOTR was out in film — and the conversation turned on the fact that neither of them understood why the heck it was so popular — what did it mean, what in our culture made it so gripping? I felt I didn’t explain it well — or couldn’t get it across the barrier, so I never really stopped thinking about that conversation.
So — there it is. All I can tell you is there are reasons — and Western/European mythology has a different point of view from Asian/Chinese mythology. My cousin is as American as I am, but his interests and the course of his life are not as mine. His wife is an amazing woman, but I find her novels tough going — no mythology involved. So 
Sorry if this is TLDR — I got interrupted several times, as often happens.
All the best in whatever it is you like to read — not everyone is keen on Elves and Wizards. 
I had to Google Luigi Mangione just now to figure out what thread was about! 
Happens to me here all the time. Now I have o go get caught up!
We had a kid in our little league baseball that chased after a umpire with a baseball bat because he thought a strike was a ball.
VIOLENCE does not solve anything.
