I agree, that was (supposed to be) my point, too. ‘Murder is wrong in every case, no matter the context’ is too black and white, and just sitting on a high horse and preaching won’t remedy the underlying situation. The trolley problem exists for a reason. The French revolution was supposed to be the extreme counter example to disprove OP’s stance, since most people will look at the French revolution as justified and necessary, but murder was very much part of it.
The ‘violent revolution inevitable’ quote was meant to show that it’s still a last resort, but alas, we’re apparently approaching that point.
