Banquo is a Ghost

MacBeth as king. Well he doesn't even gain his power morally so how will we expect him to keep his power morally. MacBeth killed Duncan to become king and now he faces the truth of Banquo's sons becoming king and him not having sons to be heirs to his throne. With the little blood on his hands from his first murder he now believes that he can kill anyone to keep his power. He calls upon murderers to do the deed on killing Banquo and his sons because he and Banquo have friends in common and he doesn't want to be blamed if he killed Banquo himself.. The murderers completed part of the task by killing Banquo but his son was able to make it out alive. Although MacBeth believes he can kill anyone to keep his power he does experience guilt. Like with the imagining of the dagger before killing Duncan he imagines Banquo's ghost at dinner. Lady MacBeth is forced to provide explanations for MacBeth's strange behavior and sayings. She tells them that he has experienced these fits since he was a child. Lady MacBeth knew about the murders but she wasn't very fond of them like she was for the murder of Duncan. MacBeth is very full of himself with his great deal of power.
