Answer:
1. Lady Macbeth:
She is a very confident woman, which is obvious from the way she thinks and fights for her husband. She is very ambitious and wants Macbeth to have a more prominent role in the kingdom. At times, she curses his lack of ambition and confidence and wishes she was a man so that she could do all of these things on her own instead of relying on her husband.
On the other hand, when she and Macbeth commit their first murder of Duncan, she loses that confidence and starts not only doubting herself and their cause, but also feeling great guilt that drives her to madness.
2. Macbeth:
On the other hand, Macbeth initially lacks confidence and ambition. He relies on his wife to tell him what to do and how to fight for what he (or rather she) wants.
However, as time goes by, he becomes more and more confident, especially after the prophecy from the witches and the killing of Duncan. After his first murder, he cannot seem to stop and is driven by crazy ambition, which results in everyone's death.
