In Julius Caesar, what do we know from Caesar's habit of referring to himself in third person?

Quite simply, it is Caesar's way of elevating himself
above everybody else, god like almost.  He is the only character in the play to speak of
himself in the third person.  In his mind, he is already emperor of Rome, and all that
remains is the formal ceremony.  That he refuses the crown three times is part of his
strategy.  It just makes the people want him more.

Cassius
is correct in his observation of Caesar when he is trying to convince Brutus of the
danger he poses to Rome.  He compares him to a Colossus striding through Rome implying
stepping on others along the way.

Are Cassius's fears
correct?  One has only to look at the history of Rome and the change from a Republic to
an Empire to find the answer.
