Question

what traits of brutus' character lead him tp make a strategic mistake

Answer 1

 he allows himself to be brought into the conspiracy and misled by Cassius into thinking there are more people in support of their actions than there really are. This Cassius does by throwing in fake letters at Brutus's window, signed with various names, in the days leading up to the assassination.A second and very large mistake is that Brutus agrees to let Marc Antony speak at Caesar's funeral. Cassius has serious misgivings about this and warns Brutus inAct III, scene i, after Antony makes his request, not to agree"You know not what you do: do not consentThat Antony speak in his funeral:Know you how much the people may be movedBy that which he will utter?" (Act III, scene i)However, Brutus does not listen. He is confident that, if he speaks first, there will be no problem,

also,he allows antony to address the romans which hatches their evil strategies
