Answer:
Lady Macbeth and Macbeth both waver between extreme confidence and great doubt throughout the play because they are constantly in the unknown of whether or not Macbeth will become king, and along the road of them trying to make him become king they have moments where they feel as if it is easy to achieve their goal and others where they may get caught.
In Act 1 scene V Lady Macbeth has received a letter from Macbeth. In the letter Macbeth speaks about how he has come across three witches that have supernatural abilities to tell the future; they have told him a prophecy stating that he will become the Thane of Cawdor which is basically a king. Lady Macbeth then goes on to tell the audience that Macbeth will be the king, and that she does not believe that he has what it takes to seize the crown because he is to good hearted "yet do I fear thy nature;It is too full o' the milk of human kindness To catch the nearest way: thou wouldst be great;" in this quote Lady Macbeth is having doubt that Macbeth will not be able to become king. Throughout the scene Lady Macbeth continues to tell Macbeth that if he wants to be king he is going to have to be ruthless, and that he may be too much good natured to cheat his way to the crown. At the end of the scene she changes from being unsure if it is possible for him to be king to more confident when she says "Hie thee hither, That I may pour my spirits in thine ear;
And chastise with the valour of my tongue" this quote is saying that she wants Macbeth to come home soon so she can talk with him about how they are going to pull this off and talk him into cheating his way to the crown by killing the Duncan.
In Act 1 scene VII Macbeth is talking and debating whether or not he should kill the Duncan to become king and the morality of it. In the beginning of the excerpt from the scene Macbeth says "He's here in double trust; First, as I am his kinsman and his subject.." in this quote he is saying that the king trust him and that he is one of his kinsman and he is feeling wrong about wanting to kill him, even though earlier in the play he had been saying that he wants to kill him quickly to get it over with. Throughout the whole excerpt of the scene Macbeth is feeling guilty and saying how wrong it would be to kill the king because he is a good leader, however at the end he changes from having doubt about killing the king to confidence in his ambition to become king that he has the murderous side in him to do it.
Lady Macbeth and Macbeth have moments of extreme confidence as if it will be easy to kill the Duncan and Banquo and then their humanity gets to them and they have moments of doubt because Macbeth knows it is wrong and Lady Macbeth is so power hungry she cannot see its wrong.
