The text provides several details that suggest the narrator's critical view of Scrooge. Particularly, the description of Scrooge's physical state—"The cold within him froze his old features," "nipped his pointed nose," and "made his eyes red"—paints a stark picture of a man who is not only miserly but also emotionally and spiritually frozen. This imagery reflects his character and suggests that his avarice has negatively impacted his very being.
Additionally, the mention that "Scrooge never painted out old Marley's name" illustrates his unwillingness to let go of his past and his connection to Marley, who represents the consequences of a life lived without generosity or compassion. This aspect emphasizes Scrooge's resistance to change and his attachment to his mercantile identity, which the narrator seems to critique.
Overall, through these descriptions, the narrator conveys a sense of disdain toward Scrooge's character, highlighting the coldness, isolation, and lack of humanity that define him.
