In the rest of the play, Macbeth is often portrayed as a coward, often unwilling to go through with a plan. His sudden display of bravery is very new, perhaps driven by his insanity.
It's more important to what a person does because as they say, actions speak louder than words do. A person can think a certain way but not act on it but what a person does reflects what they decide internally and what they wanted to do with that idea externally showing that they are serious with that idea of theirs in their head.
Macbeth's strengths contribute to his downfalls because he was once honorable and strong. He let his curiosity get the best of him and as time over goes you see that he is conflicted between his good traits and his bad ones. So you see his honor slowly fades away. Macbeth (in the beginning) wants to do good but his wife pushes him into an evil monster and transforms him into an evil being.
