Interesting read.
I don't have much to add to it aside on this
>You can’t shoot people you disagree with, and you can’t shoot people to solve your disputes. That is not the society that I want to live in. I hope the person who did it is found. I hope they are put in prison, and I hope they enjoy spending their life there because that’s the world that we should live in. We don’t. We don’t want to open that box that is a bad box to open

As morally valid it is you can also spin it like this:
"You can’t deny medical refund to people you disagree with, and you can’t ignore their demands to solve/augment your return on investment for shareholders. That is not the society that I want to live in. I hope the person who do it is found. I hope they are put in prison, and I hope they enjoy spending their life there because that’s the world that we should live in. We don’t. We don’t want to open that box that is a bad box to open "

It's as morally wrong to deny medication to people who are asking/paying for it, it's a form passive violence, as much as it is morally wrong to remove the issue that blocks that with physical violence.
Because in either case it ends up with more passive and physical violence.

But you also have to acknowledge that in some cases, where all reason, all possible dialog where people refuse to listen and be reasonable to pleas then it is also normal to be able to defend yourself, first legally, and if that fails then sadly only a physical intervention is possible.
But like stated in the blog post it's quite suspicious that this man was currently under several investigations and that the "murderer" was found so quickly and with massive evidence.
