Beatus autem esse sine virtute nemo potest - Cicero

Sed tamen ira procul absit, cum qua nihil recte fieri nec considerate potest.

Here you have a man who desired to be king of the Roman people, and who accomplished his purpose. Whoever says that this desire was right, is mad; for he approves of the destruction of laws and of liberty, and deems their foul and detestable suppression glorious. But as for him who acknowledges that it is not right to usurp sovereign power in a state which was and which ought to be free, yet that it is expedient for him who can do so, by what remonstrance, or rather by what reproach, can I strive to draw him back from so grave an error? For (ye immortal gods!) can the basest and foulest parricide committed upon his country be expedient for any man, even though he who has made himself thus guilty be called parent by the citizens whom he has brought under the yoke? Expediency, then, ought to be measured by the right, and so indeed, that the two, though expressed by different names, may have to the ear the same sound. I do not accord with the opinion of the multitude who ask what can be more expedient than the possession of sovereign power; on the other hand, I find nothing more inexpedient for him who has obtained this power unjustly, when I begin to recall reason to things as they really are. For can anxieties, solicitudes, terrors by day and by night, a life crowded full of snares and of perils, be expedient for any one? Attius says,"The throne has many faithless, loyal few."

O ye immortal Gods, where on earth are we? In what city are we living? What republic is ours? There are here,—here in our body, O conscript fathers, in this the most holy and dignified assembly of the whole world, men who meditate my death, and the death of all of us, and the destruction of this city, and of the whole world.
