The state has convicted and executed innocent people. The average criminal subject to capital punishment has killed an order (or several) of magnitudes fewer people than the health insurance industry.
As a country we seem to weigh more heavily acts of individual violence than those of systemic violence or violence borne of policy even when the latter 2 have far more impactful and wide spread negative results. It’s completely logical to draw a distinction between the 2 circumstances.
I’m not saying all vigilante justice is good, and I wouldn’t necessarily be against the state holding to account executives who have produced systems and policies that result in the harm or death of the state’s citizens, but in the current system justice is rare and in this act millions of people received justice.
Class war is war.
The US has literally bombed its citizens on 2 occasions because of class resistance. The military has literally taken up arms against the citizens it swore to protect over class differences. We describe violent clashes between workers and the bourgeoisie as “battles.”
Just because we’ve experienced a period of unprecedented peace doesn’t mean class conflict is over–it will not be over until class is abolished.
Also, revolutions, civil war, and war in general are most often illegal.
