The dominant general theme of this Act is that of political strife, and its detrimental effect on personal relations. The utterly ruthless nature of power politics is shown in the first scene, with Antony, Octavius and Lepidus compiling a hit-list of those they want killed. This includes Lepidus' own brother. Thus, even family relationships are seen to lose their sanctity when power is at stake. Similarly, in the next scene Brutus and Cassius's friendship is shown to be under great strain following the assassination of Caesar and the descent into civil war. They have a bitter quarrel, although they do finally make up.
