Comparison of Dion and Brutus

But Dion either chose unwisely and entrusted himself to bad men, or else treated the men of his choice so as to turn them from good to bad, neither of which mistakes a prudent man ought to make.

And in fact Plato censures him for choosing such friends as proved his ruin.

Further, no one arose to avenge Dion’s death; but in the case of Brutus, Antony, an enemy, gave him illustrious burial, and Octavius, an enemy, actually took care to preserve his honours.
