Is there something that would happen in a Dresden book that will make you quit?

I expect so see both nods to the ST:TOS "Mirror Mirror" episode, and the old Jimmy Stewart "It's a Wonderful Life" movie:  Harry will get to see some of the upsides of him having been stubbornly a "Good Guy," by was of how much darker Mirror!Harry's Chicago is.

Murphy, in particular -- stuck in SI getting Black Cat cases, but without a reliable ally/guide in Harry Dresden.  Mirror!Murphy will know Mirror!Harry as one of the Bad Guys. 

She'll be a harder, colder, less-trusting Murphy.  One with less hope.  Fighting against the encroaching darkness without any of the info she got from Harry.

A very, very different person... named Karrin Murphy.

Yup, I was going to mention "It's a Wonderful Life" as well.. What I worry is all this anticipation for a book which it cannot in any way match... I foresee a lot of pissed off readers!

Let me give you some back ground to this question. I have a very eclectic taste in books. In no particular order my top five is Watership down, K is for killer, Pride and prejudice, 1984 and one for the money. For the longest time Butcher and Evanovich were my top authors. Until her last book. I was so mad at her choice of husband ( straight married white guy that likes rom coms here ) that I may never read another of her books EVER AGAIN. Which got me to thinking. What would have to happen for mus to not read another Butcher book? Thoughts?

Already kind of happened: Murphy's death and the treatment of her and Thomas', and just the whole Peace Talks/Battle Ground trying so hard to replicate MCU's End Game vibes. That, already killed 95% of my interest in the series. I'm going to stick around for Twelve Months, with that 5% of hope, but if I see any hint of Harry/Lara actually becoming a real thing, or Malcolm Dresden not being "just a very good man", I'm out, probably.

You make some very good points, especially like, Murphy is dead, but hey we will take her to Valhalla so she fans will continue to have hope and keep reading...
