What does the dialogue between cassius and brutus reveal about their characters

First of all the dialogue reveals that Brutus is weaker than Cassius, who is more determined.He has feelings for his firend Caesar, and his feeligs for him seem to be stronger than his sentiments for Rome. He does not want to be a traitor to his own heart. But Casuis tries to convince him that it is the hour of Rome  , and consequently, he has to put his friendship with Julious Caesar aside.Cassius is more decided  and in a sense, less romantic. Ambitious and a truly patriot, he uses expressions to convince Brutus that the killing of Julious Caesar is necessary for the growth of Rome" Men are at some times the masters of their fates.."He feels that it is Julious Caesar who is growing powerful, not their beloved Rome. .."Why, man he doth bestride the narrow world ..Like a Colossus.."He deems necessary to commit treason in order to free Rome of a future dictator..." So vile a thing as Caesar..".Cassius could be flattering Brutus in order to get him act, that is also revealed in the dialogue.
