Why do you think Edmund had such a bad attitude chapter 7

I think that Edmunds attitude in chapter 7 is consistent with his attitude through much of the book. Edmund is the second youngest of the children, and is cruel to his younger sister, Lucy, making fun of her story about the wardrobe and Narnia. Peter and Susan both feel that Edmund is becoming a "bad sort". From the start of Chapter 7, Edmund's skeptical nature is underscored by his inability to understand that the beaver is benevolent.
