I taught Sophs Julius Caesar for 8 years before I decided I wanted to be able to afford food and shelter. Your analogy is dead aim on. 'Friends, Romans , countrymen lend me your ears. I come not to upgrade the offense but to hand the ball up the middle on 3rd and six!'
And that's another part that I left off the original post: the plotters have to have their successor Caesar ready to go the second Caesar is dead, otherwise it's anarchy as the people cast about for a leader and begin to think they actually have some power.
And in the masters chambers they gathered for the feast, They stab it with their steely knives but they just can't kill the beast
