Chaotic Good

Historically when 'tyrants' were killed they were usually inside jobs

If by "inside job" you mean "killed by people they hung around every day, some of whom were just slaves", then yeah.

The killing of evil powerful people by the common rabble like you and me is such a rare celestial event

That's just plain incorrect.

Read it through. A significant portion were killed by their "employees" and the people in general. Servants, captains, hell, there's even one monarch killed by two shepherds.

Ofc kings wouldn't walk about town like the healthcare CEO did, but the reason the royalty didn't do that, is because unlike the CEO, the monarchs knew they'd be killed. That is unless you're with a retinuen armored men and safe in a carriage. And only eat the leftovers from your tasters, because you're afraid of literally every meal being poisoned by a disgruntled subject.

The new "kings" as in the capitalists, they don't properly have this fear yet. Whoever Luigi is protecting (because there's no evidence he did it) just reminded the "nobility" of how things used to be.

Hell, one of the first murderers in that list is a person who's a prophet in Judaism, Christianity and Islam; Samuel.

Also, have you forgotten what the people did in France a few hundred years ago?

Basically our whole system is based on the people having taken power with a violent uprising against the evil douches.

The killing of evil powerful people by the common rabble is incredibly common throughout history.

Stop spreading apathy.

Andor | Karis Nemik’s Manifesto

There will be times when the struggle seems impossible. I know this already. Alone, unsure, dwarfed by the scale of the enemy. Remember this. Freedom is a pure idea. It occurs spontaneously and without instruction. Random acts of insurrection are occurring constantly throughout the galaxy. There are whole armies, battalions that have no idea that they've already enlisted in the cause. Remember that the frontier of the Rebellion is everywhere. And even the smallest act of insurrection pushes our lines forward. And then remember this. The Imperial need for control is so desperate because it is so unnatural. Tyranny requires constant effort. It breaks, it leaks. Authority is brittle. Oppression is the mask of fear. Remember that. And know this, the day will come when all these skirmishes and battles, these moments of defiance will have flooded the banks of the Empire's authority and then there will be one too many. One single thing will break the siege. Remember this. Try.
