Why was mark Antony becoming selfish?

Mark Antony's increasing selfishness can be attributed to his desire for personal power and ambition following Julius Caesar's assassination. He sought to consolidate his influence in Rome and pursue his own interests, often prioritizing his relationship with Cleopatra over his political duties. This shift in focus led to a decline in his reputation and support among Roman citizens and allies, ultimately contributing to his downfall in the struggle for control of the Roman Empire.
