I think you’re right about the FAFO bit. I suspect Mangione will end up being simply the first. I mean that as a prediction, not an endorsement. Anyone who’s studied the French Revolution knows how these things can turn out, for many the same reasons.

But I’ll almost always be against vigilanteism outside extreme hypotheticals (“would you shoot Hitler?”). Even if I were morally ok with a specific instance, some time the person behind the gun might disagree with someone I support, and then where’s my moral ground to oppose their actions?

Edit: Furthermore, as much as I despise UHC and their leadership, I love the notion of our justice system more than I loathe them. When someone decides to be the judge and executioner, society devolves to “might makes right”. I served in Somalia. I don’t want to live there.
