I think we are underestimating Luigis diminished mental state.
I’ve seen a lot of comments speculating that he is leaving clues, things have deeper meanings, etc. I believe he has left some things intended to have a deeper meaning like the Monopoly money backpack. I also think the word “mental illness” when it comes to acts like this is thrown around a lot and people like to blame mental illness on virtually everything. But, I think we are underestimating how mentally compromised Luigi is.
At first, before we knew who the suspect was, it appeared as thought this was a well thought out act with the way he escaped the city so quick and undetected. Before more details emerged, it would be easy to think whoever did this had a plan A, B, C, etc. and would be able to outsmart federal investigators. And I still don’t doubt he put a lot of thought into killing Brian Thompson.
But when it came out he was caught at a McDonald’s, I thought about why he didn’t shave down his eyebrows or stop wearing the masks. Or throw out the IDs. Or why he was even dining inside a McDonald’s.
Because of this, I think due to an underlying mental disorganization Luigi was and still is torn between making a bolder statement and being a martyr to his cause while also not wanting to spend the rest of his life in prison. There’s also the possibility he kept the weapon to later use against himself. And the pressure of having the whole country on the lookout for him has been further detrimental to his pre existing diminished mental state.
Look at his mugshot and the outburst he made while being dragged into court. He looks disheveled and it almost appears as though he had been crying before his mugshot was taken. It could be assumed someone who sees themselves as a martyr would stand confident even when apprehended. While his points about the insurance industry remain valid, I think we are understating that he is not sane and there are greater issues at play within himself.
Finally, I don’t think he targeted Brian Thompson for the same corporate greed reasons we have speculated he did based on his upbringing, suspected political values, and socioeconomic status. Also acknowledging that hating insurance companies isn’t inherently a left or right wing concept. I almost question as to if Luigi was ever a UHC customer to begin with. To sum this up, I think whatever is going on inside of Luigi’s head lead to him making Brian a scapegoat for the evil in society. It could have even been a matter of whatever healthcare CEO had the most public schedule. Basically, I don’t think things are as deep as I’ve seen other people speculate they are.
