Macbeth Act Three Reading Journal

Scene 1:
Banquo fathoms the Witches prophecy that he and Macbeth shall be Kings and the subsequent fulfilment of Macbeth's fate begs him to consider what will happen to his own fate. So too does Macbeth begin to consider the very same idea, beginning to fear his own betrayal by Banquo "a barren sceptre in my grip, Thence to be wrenched by with an unlineal hand," resulting in his decision to have Banquo murdered. Macbeth feels as though his betrayal of his King has been in vain because it is just a step for Banquo’s lineage to take over "For them the gracious Duncan have I murdered,” Macbeth's murderous tendencies have manifested that he begins to become indifferent to more bloodshed.
Scene 2:
This scene is a pivotal moment for the characters Macbeth and Lady Macbeth as Macbeth becomes the bolder and more malicious of the two, having to carry their dark deeds as Lady had done. It's as if they have switched roles which is reinforced by the way Macbeth stirred the murderers in Scene 1 by questioning their manhood as Lady had done to Macbeth in Act Two.
Scene 3:
Banquo is murdered by Macbeth's employed murderers but his son Fleance escapes.
Scene 4:
Upon report that during the murder, Fleance escaped, Macbeth fears that the boy will persist as a problem "The worm that's fled Hath nature that in time will breed,” As the dinner arranged by Macbeth with several Lords continues, Macbeth envisions the ghost of Banquo, causing much alarm for him, Lady and the guests. The vision of a bloody and dead Banquo shows Macbeth's guilt for the murder of his friend. The fact that Macbeth fully believes Banquo is present shows his deeper descent into madness whereas in Act Two Macbeth was able to question his apparition of the dagger "Avaunt, and quit my sight! Let the earth hide thee!” Macbeth's lust for power have taken over him and all his previous morals, he shows little to none hesitation in acting upon the murders of yet more people "We are yet but young in deed."
Scene 5:
The Witches are visited by Hecat, the goddess of witchcraft. Though Hecat denounces the Witches for acting without her consent, she orders the witches to create visions for Macbeth that will make him doubt his security. The presence and intervention of Hecat, an entity more evil than even the Witches, foreshadows that greater sins are to come.
Scene 6:
The lord, Lennox speaks with another lord over the deterioration of Scotland It is revealed there is suspicion for Macbeth to be the murderer of Duncan and Banquo and that Macbeth is unloved by his peers, contrary to Duncan.
