Caesar’s hubris is used against him, there is evidence of this in act 2 scene 2.

‘ ‘Break up the senate till another time, When Caesar’s wife shall meet with better dreams.’ ‘

Decius Brutus is questioning Caesar’s sense of identity, which is linked to his pride. Caesar’s wife has persuaded him to stay home tonight because she had bad dreams. Caesar’s pride is used against him because Decius wants him to  come to the senate so the conspirators can kill him. Decius wants to make Caesar feel like his wife is in control which questions his ego and of course Caesar’s ego and masculinity comes before his wife’s concerns.
