Therefore Dion was not trusted even by all his friends, who felt that after removing Dionysius he might secure the government for himself, enticing his countrymen along by some milder name than that of tyranny;
but the enemies of Brutus were wont to say that of all the conspirators against Caesar he alone had one aim from first to last, namely the restoration to the Romans of their ancient form of government.
However, apart from these considerations, the struggle against Dionysius was surely unlike that against Caesar.
