Antony And Cleopatra - Betrayal

Betrayal:

I think, in this instance, the political and romantic betrayals go hand in hand. Cleopatra's betrayal at sea destroys Antony's credibility. Antony's reunification with Cleopatra after he marries Octavia is a romantic betrayal to both Caesar and Octavia. Most of all, Antony's reception to the marriage to Octavia in the first place is a source of betrayal (maybe one less political, but nonetheless):

CAESAR

Say not so, Agrippa.

If Cleopatra heard you, your reproof

Were well deserved of rashness.

ANTONY

I am not married, Caesar. Let me hear

Agrippa further speak. 

In the case where Antony wishes to kill Cleopatra, I believe it is another act of a topic that was discussed earlier: passion. I don't think he would have actually done it, as he is too pussy-whipped and wouldn't want to completely abandon all chances of winning against Caesar. 

When it comes to political loyalty in this play, I believe that those who serve their leaders do so because of how they know them. Caesars men all have great respect for Caesar, and Antony's act likewise. The loyalty to each man is based off of their past deeds, and some go far as to kill themselves than see they leaders dead or totally disgraced (as evidenced by the guy who killed himself instead of Antony. Don't judge me I forgot his name).

In Enobarbus's case, I think it was his rational reaction to an irrational man that led him to desert. Though he loved Antony and believed in him, he knew the path he was on was self-destructive. I think that's why he ultimately deserted and betrayed him. As we know, it caused him so much emotional anguish that he died. What a loser. As to who's at fault in this situation, I can't really say. Obviously Enobarbus didn't need to betray him, but he was driven to do so by Antony. I think it's both of their faults. 

When we talk about Antony's loyalty, we're talking about two things: where it is, and where it should be. Obviously it is with Cleopatra (though I personally think it should be with Rome). Though his words above might indicate otherwise, he's been loyal to Cleopatra throughout the play. His passions wish for her death, but he ultimately crawls back to her (literally and figuratively). I think he believes his duty to Rome is be ruling it. I really didn't get any kind of sense that he was loyal to anyone but Cleopatra and his own cause. If he had defeated his enemies and been victorious, I'm sure he would've been able to remain loyal to Rome, Cleopatra, and himself (but the capital of the Empire would've moved to Egypt so Cleo wouldn't bitch so much).
