I am trying to analyze the quote from Macbeth:
“Thou hast it now: king, Cawdor, Glamis, all,
As the weird women promised, and, I fear,
Thou play'dst most foully for't"
I am struggling to find particular words to analyze that link to betrayal or ambition. Help?
In terms of ambition leading to betrayal, the last line is the most relevant part. Saying that Macbeth played foully for all the titles he has at this point in the story is emphasizing that he has been competing (playing) but with some sort of unfair (foul) advantage. The last line also emphasizes that Macbeth is so focused on winning this "game" that he will betray anyone or anything that would try to impede him from achieving his ambitions. You could definitely look at the words "I fear," also, since those are relevant to the idea of betrayal that has already occurred as well as betrayal that is yet to come in the narrative.
