So I'm writing an essay on the play Macbeth and I really need some help. I've already got the beginning started with a thesis but for 3 of the paragraphs I need 3 key points relating to my topic: manhood. So I've decided for each paragraph I could talk about the characters who question his manhood one of them being lady macbeth but I need 2 more people. would the witches be one of them?
