What might you conclude that macbeths character is not all bad

Macbeth is presented as an honorable, courageous soldier, who valiantly fights for King Duncan. Only after meeting with the Three Witches does Macbeth's ambitious nature begin to develop. Despite his ambitious feelings, Macbeth is still a loyal soldier and is ashamed to admit his thoughts about murdering the king.
