According to Brutus, why is an oath among the conspirators unnecessary Brutus does not want to swear an oath because this would lessen the nobility of their endeavor

Answer:

Explanation:

Brutus does not want to swear an oath because this would lessen the nobility of their endeavor.  As honorable and honest men—good Romans all, they are pledging themselves to commit an honorable deed by killing Caesar; an oath would suggest that they lack nobility, honest, and courage. He says “Not an oath. / If not the face of men, /The sufferance of or souls, the time’s abuse,/ If these motives weak, break off betimes, And every man hence to his idle bed.” If their cause is not just in itself, then they shouldn’t kill Caesar to begin with. And then he adds, “What other bond / than secret Romans that have spoke the word and will not palter” (2.1.125-137). We can infer that Casca is a bit "dull," because Cassius tells us he is back in Act 1 and we see him only agreeing in Act 2.1 (52-55). We can infer that Cassius is a very clever politician because he realizes the danger Antony presents and wants to kill him too 9169-174). We know Brutus is noble but not a savvy politician because he refuses to kill Antony, and this decision results in great trouble as the play proceeds
