Why does Caesar decide to go to the Senate despite his wife’s warnings?

Caesar goes to the Senate because his ambition surpasses his desire to comfort his wife. After Calpurnia’s terrifying nightmare that portends Caesar’s assassination, Caesar initially agrees to stay home, despite his belief that nothing can change his fate. Midway through the scene, Decius—one of the conspirators—arrives to escort Caesar to the Senate. Not wanting to lie about the reason he refuses to attend, Caesar informs Decius of Calpurnia’s dream. Knowing that he needs to convince Caesar to come, Decius tells two lies. First, he reinterprets Calpurnia’s vision, insisting that the blood in her dream does not represent death, but instead represents the life and renewal Caesar will bring about for the Romans. Second, Decius says the Senate plans to crown Caesar the first emperor of Rome. Decius’s two lies stoke Caesar’s thirst for power and convince him to go to the Senate despite Calpurnia’s warnings, ultimately leading to Caesar’s doom.
