When all other avenues are blocked, (like they are, don't pretend the average person has any recourse) it becomes an option

When did killing people become a solution?

Since the beginning of time.

We're animals after all.

It became a solution when we got results.

Also take a step back and look at human history. When have we ever actually gotten progress through anything but violence?

Those who make peaceful progress impossible, make violence inevitable. Brian Wealthcare over there was never going to see the inside of a courtroom, much less a jail cell, so vigilantism is the only recourse left. The bourgeois controls the other three boxes, but they'll never control the ammo boxes
