In the play Hamlet by William Shakespeare, the Ghost of King Hamlet appears to Hamlet and offers him guidance and information about his father's murder. While the Ghost does not explicitly instruct Hamlet to punish his mother, Gertrude, for her role in the murder, it does express its disappointment and disapproval of her actions.
To confirm this, you can refer to the text of the play, specifically Act I, Scene 5, where the Ghost appears to Hamlet. Here, the Ghost reveals that it was murdered by Claudius, Hamlet's uncle and Gertrude's new husband. The Ghost emphasizes the importance of avenging this crime by saying: "If thou hast nature in thee, bear it not. Let not the royal bed of Denmark be a couch for luxury and damned incest."
Although the Ghost emphasizes the importance of avenging his murder, it does not explicitly mention Gertrude in relation to the act of revenge or instruct Hamlet to punish her directly. However, Hamlet interprets the Ghost's words as a call to confront his mother about her hasty marriage and involvement in the murder.
It is essential to note that interpretations of the Ghost's instructions may vary among readers and productions of the play. Therefore, it is always worthwhile to study the text yourself and consider different critical perspectives.
