That's what I've been wondering, we really don't even know what the motive was, but the one thing that kind of elevates this beyond him being a "basic murderer" is the carved words on the bullets. That seems to suggest some kind of motive above just him being a hitman or just killing some random person.

Regardless, I think most people are having the reaction they're having to this because of our ridiculous healthcare system, everyone recognizes it as a problem and alot of people have a loved one who has been wronged by it. Almost any other issue would've created a partisan split where Republicans took one position and Democrats took the other position. That a set of clear Left/Right narratives haven't emerged yet kind of suggests that alot of people aren't particularly bothered by it. Where this goes though is anyone's guess, maybe it's just a single unified moment that is quickly overshadowed by some other bullshit that comes along.
