Having Brutus as one of the conspirators will strengthen the conspiracy against Caesar. The public will support the conspirators because Brutus is an honorable man. Casca states how important it is to have Brutus on the conspirators' side. He recognizes the honorable qualities the Brutus possesses:
O, he sits high in all the people's hearts!
And his face, like the best method of changing
Water to gold, will change whatever seems
To be offensive in us,
To goodness and to worthiness.
