Book 2.20

The question has been raised, whether Marcus Brutus ought to have received his life from the hands of Julius Caesar, who, he had decided, ought to be put to death.

As to the grounds upon which he put him to death, I shall discuss them elsewhere; for to my mind, though he was in other respects a great man, in this he seems to have been entirely wrong, and not to have followed the maxims of the Stoic philosophy. He must either have feared the name of "King," although a state thrives best under a good king, or he must have hoped that liberty could exist in a state where some had so much to gain by reigning, and others had so much to gain by becoming slaves. Or, again, he must have supposed that it would be possible to restore the ancient constitution after all the ancient manners had been lost, and that citizens could continue to possess equal rights, or laws remain inviolate, in a state in which he had seen so many thousands of men fighting to decide, not whether they should be slaves or free, but which master they should serve. How forgetful he seems to have been, both of human nature and of the history of his own country, in supposing that when one despot was destroyed another of the same temper would not take his place, though, after so many kings had perished by lightning and the sword, a Tarquin was found to reign! Yet Brutus did right in receiving his life from Caesar, though he was not bound thereby to regard Caesar as his father, since it was by a wrong that Caesar had come to be in a position to bestow this benefit. A man does not save your life who does not kill you; nor does he confer a benefit, but merely gives you your discharge.
