The first Quote I chose to analyze is, "If chance will have me king, why, chance may crown me, without my stir." This quote directly means if the sisters are telling the truth then I will become king without me having to interfere. This is an important quote because throughout the first two acts Macbeth has an internal battle over whether or not he should kill King Duncan, and this is a hint of whats to come.
The second quote I chose to analyze is, "If it were done when 'tis done, then 'twere well. It were done quickly: if the assassination Could trammel up the consequence and catch with his surcease success; that but this blow Might be the be-all and the end-all here." The meaning of this sentence is if the murder were done when The sword killed him, then it would best be done quickly but that isn't the end. The end would be if the murder was done without consequence, and only bringing success, then the killing would be the be-all and the end-all. This is important to Macbeth's internal struggle because after he has killed King Duncan, he thought the end of their troubles would be over as soon as his heart stopped beating, but it didn't.
