How is Caesar’s Hubris used against him?

Caesar’s hubris is used against him in Act 2 Scene 2 where he is speaking to his wife and promises not to see the Senate that day. However once Decius Brutus arrives to collect Caesar, his mind changes because Decius tells him that ‘the Senate have concluded to give this day a crown to mighty Caesar’. The quotation can be explicitly interpreted to tell us that the Caesar may lose the crown if he does not turn up. Once he realised this, he went against his wife and said ‘How foolish do your fears seem now, Calpurnia! I am ashamed I did yield to them’. This suggests that Caesar puts his pride above everything as he goes against his word to ‘claim’ the crown. However, it was a lie created by the conspirators to get Caesar in the right place for them to murder him.
