Cassius and Brutus were arguing about who was taking bribes, in doing this they were of course blaming each other.  Brutus was only angry because Portia had recently died.  Cassius admitted that he also was only mad. Neither of them would most likely do such a thing, in the words of Brutus "I had rather be a dog and bay the moon than such a roman" Yet Brutus is an honorable man.
