Brutus trusts the crowd to be as loyal to Rome as he is. It never dawns upon him that a true assassin does not kill for love of country, but kills out of hate, envy, or other misguided motives. Brutus never possesses the true character to be an assassin, and after he addresses the crowd he firmly believes that the crowd will believe his reasons and will accept this explanation. It is as if he lives in a world of fantasy where all people are loyal and love their country, and no one is more ambitious than they should be. Throughout the rest of the play, Brutus always wants to do the noble thing. Assassins never do the noble thing.
