Not only is it that murder is ok for everyone at a certain point but its that we are conditioned to praise retributive violence and killing so long as the ones being beaten maimed and or killed are marginalized people whom the ultra wealthy see as sub human and their casualty benefit their end goals. Like all the non violent labor and civil rights protestors who have ended up bludgeoned by batons and less than lethal munitions, or targeted by extra judicial unconstitutional surveillance and suppression tactics such as yale used against pro Palestinian demonstrators over the last year. There are too many examples of this double standard to go over without writing a book as thick as the king james Bible.
If the universal law became such that those being systematically exploited and ultimately sickened and or killed by systemic injustice could target those benefiting from the injustice then those incentivizing and committing the act of social murder would be incentivized to rethink their approach to profiting off the death and suffering of poor and marginalized people.
We seem to overlook that FDR’s new deal and the Fair Labor Standards act of 1938 was enacted as a compromise to prevent more violent rioting by the frustrated and exploited laborers during the gilded age. It was either the robber barons acquiesced to what was good for those doing the work giving them a fairer deal or those they were exploiting ruthlessly would have dragged them out into the streets and beaten them senseless or worse in front of their wives and children.
