As to the second question, whether the advantage to be derived from the example was such as to justify an act of such violence, it appears to me to be a complete solution of it to observe that, with respect to England (and I know not upon what ground we are to set examples for other nations; or, in other words, to take the criminal justice of the world into our hands) it was wholly needless, and therefore unjustifiable, to set one for kings at a time when it was intended the office of king should be abolished, and consequently that no person should be in the situation to make it the rule of his conduct. Besides, the miseries attendant upon a deposed monarch seem to be sufficient to deter any prince, who thinks of consequences, from running the risk of being placed in such a situation; or, if death be the only evil that can deter him, the fate of former tyrants deposed by their subjects would by no means encourage him to hope he could avoid even that catastrophe. As far as we can judge from the event, the example was certainly not very effectual, since both the sons of Charles, though having their father's fate before their eyes, yet feared not to violate the liberties of the people even more than he had attempted to do.
