Question

Which character is confident he can get caesar to leave his house and go to the capital that day?

Answer 1

Note alternate answers concerning Caesar's vanity, his self-importance, his carelessness. Decius knows unequivocally which catches to push. Then again, maybe this is the day that Caesar will kick the bucket, regardless of how he tries to maintain a strategic distance from his destiny. Consider what number of different circumstances destiny appears to assume a part: Cassius kicks the bucket on his birthday, Antony's prediction about the "pooches of war" works out as expected, Caesar's phantom shows up twice to Brutus, Cassius sees the prophetic falcons supplanted by forager flying creatures. 
My point is that it isn't difficult to clarify Caesar's activities in light of his identity; his character blemishes. Then again, as with huge numbers of Shakespeare's plays, destiny appears to have a controlling hand also. All things considered, Caesar portentously goes to the Capitol since he should.

Answer 2

The character that is incredibly confident that he can convince Caesar, who is being extremely superstitious, to leave his home and go the capital is Decius. Decius believes that he can flatter Caesar and use his prideful and self absorbed personality against him to convince him to go to the capital.
