Is Gertrude protecting Hamlet when she says he is mad (4.1.7) or does she believe that he is mad If she believes he is mad does it follow that she no longer feels ashamed and guilty?

Gertrude's response about Hamlet's madness can be interpreted in various ways. She may be trying to protect Hamlet from harm or trying to divert attention away from his potential danger. It is unclear whether she genuinely believes he is mad. If she does believe he is mad, it does not necessarily mean that she no longer feels ashamed or guilty about her actions, as those emotions can exist independently of her perceptions of Hamlet's mental state.
