As far as I've seen the same is no different in the Monarchosphere.
However I would like to propose the one crime we should all agree upon, as Monarchists, that should warrant the Death Penalty, the crime of Treason.
Now this opens up all sorts of questions and discussions over 'What is Treason?' and 'Who is a traitor in X scenario with X conditions?' Could Briton Rebel kings and queens that were brought to Rome for Judgement be considered 'Traitors'? Can Counter-Revolutionaries in Republics be considered 'Traitors'? I wont pretend that I will answer these for you, this post is about actually agreeing that the crime of Treason ITSELF be worthy of the punishment of Death.
Personally I say yes, (at great risk to my own legitimacy), if one commits Treason, such as assaulting a Sovereign with intent to Injury, defamation with intention to cause unrest, spying for a foreign power, etc, etc, etc, should truly warrant the Death penalty and here is why, in order of pettiest to severe:
-By these actions an Individual deceives his peers with no regard to their safety
-He ruins the good names of innocents connected to him by business dealings and Acquaintance
-He ruins the standing and risks the estate of his family, both immediate and extended, by his actions. Putting his own desires ahead of his House.
-His actions likely result in injury or death, or in the case of spying, risking the injury, death, and possible conquest of Thousands or Millions of his Countrymen.
-If he is a man of standing, he betrays the trust of the Lower classes, the trust of higher classes, and the trust of his Sovereign.
-If he is not a man of standing, he betrays the trust of all that he would be an upstanding Subject of merit, besmirching the image of the entire lower classes by his base actions, causing distrust suspicion and possible unrest within the nation.
-By endangering his Sovereign he not only shows his disloyalty to his nation and Countrymen, but a callous disregard for everything that Nation is, was or ever will be, by attacking and endangering the enduring symbol of the Nation's continuity, past present and future, that the Sovereign embodies.
All of these crimes show but a glimpse of the tremendous breech of justice that Treason causes, a breech that cannot be filled by simply languishing the Traitor in the worst jail in the Nation for his abominable crimes. Blood must be paid to satiate Justice in this regard, because it is simply not possible for Justice to be served any other way when the crime is against the Country as a whole, blood being spilled is an ugly necessity. It appeases the lower classes, and dignifies the upper classes, and all will know an ugly piece of history has been put to an end once this criminal has been killed. Obviously a Sovereign would have to careful that executing a traitor or rebel wont inspire something worse, as king George VI warned his Government against shooting the Easter Rising prisoners because he had the foresight to see what effect such an action would have, needless to say Parliament didn't listen to their King and here we are.
The rationale behind this would be lost on most republicans, (with the exception of the Americans), as they do not understand how Justice is done by killing the Traitor and not letting him suffer in jail for his whole life. Well, inevitable puns about 'Republican Justice' and the state of most modern Justice systems aside for now, Gents, the reasoning most monarchies, ESPECIALLY in Europe found behind this, was there was no more terrible a punishment for a Traitor's crimes then answering to the Divine for their crimes. And even then the condemned were given their chances to repent before God, not man for man could not forgive them, for their crimes before they met Him. Something that is lost on the modern world.
What do you say? Let us see if we can get another discussion going.
