I agree is justified in many situations, the French revolution ain't a good example for that, namely that it didn't work in the long run with all the Napoleon-ing. The people most adept at violence, who will be most empowered by violence as normalized political tactic mostly don't promote the interests of most people if they get into power. Napoleon and such
also every time there's been prominent "propaganda of the deed" it's backfired by inciting a HUGE state crackdown, Tsar Alexander II and William Mckinley come to mind ~~though both were relative reformers, which would make this about target selection and not alienating potential allies rather than the use of the tactic in general~~
I didn't make any arguements about this specific situation? Murder in general is bad
The problem is that there's no clear endpoint of that thought process. The number of people that exact thought process applies to would require a level of violence that I doubt anybody sane wants.
Edit: to be more precise here. I'm leery about trying to apply the logic of individual self-defense to broader questions about social murder. The entire system is complicit, but if we go to burn the system down without a replacement ready we'll end up sorrounded by nothing but ash and corpses
