At the end, he was so weary from everything that was going on that when he received the news of his wife's death he accepted it with only a yearning resignation.
Macbeth's whole story after Duncan's murder was one of continuous character deterioration.
Macbeth could be brave when it came to action but when he started thinking he would hesitate and would have to be urged into action by his wife or by the sense of security that he obtained from the prophecies of the supernatural.
He changed his mind five times before murdering Duncan.
He had many noble qualities as well as several tragic flaws.
He was a courageous, brave and good nobleman who was haunted by superstition, moral cowardice and an overwhelming ambition. His personal powers and strength as a general won him the battle as described by the captain,"But all's too weak:/For brave Macbeth -- well he deserved that name – /Disdaining fortune, with his brandished steel,/Which smoked with bloody execution,/Like valor's minion carved out his passage/Till he faced the slave;".(I,2)Macbeth was even undiscouraged when he was attacked by the King of Norway, "assisted by that most disloyal traitor, the thane of Cawdor.
The three points which contribute greatly to Macbeth’s degeneration are the prophecy which was told to him by the witches, Lady Macbeth influenced and manipulated Macbeth’s judgment, and finally Macbeth’s long time ambition which drove his desire to be king. "Lady Macbeth convinced her husband to murder Duncan by putting his manhood and courage at stake, "When you durst do it, then you were a man;/And to be more than what you were, you would be so much more the man" (I,7 )As Macbeth started degrading he lost some bravery (IV, 1, "That I may tell pale-hearted fear it lies").
Although he was so far courageous and brave and he is seen as the hero at the beginning of the play, his sky high ambition causes his damnation. In his fight with Macduff, some of his old courage and strength returned.
Macbeth had great ambition and wished to stand well with the world.
He had absolutely no feelings for others and he only cared about what others would think of him.
