Step-by-step explanation:
Character Analysis in Literature
Voldemort's looks and behavior are iconic and fundamentally associated with evil in the Harry Potter series. Described as having pale skin, a snake-like face, and red eyes, he exudes malevolence. Throughout the books, author J.K. Rowling uses Voldemort's ruthless actions, his disdain for anyone who opposes him, and his quest for immortality at any cost to characterize him as the antagonist. Voldemort's ambition to purify the wizarding race and to conquer death further solidifies his status as an emblem of evil.
Character development in literature often involves characters discovering wrong assumptions about each other. For instance, Harry Potter, who evolves from a lonely boy to a sociable and mature individual, initially mistakes some characters' intentions, realizing later that some presumed 'bad guys' are actually 'good guys.'
In comparison, Hagrid's looks are described in a much more endearing light. His massive size, wild appearance, and gentle demeanor with Harry and friends present him as a caring and protective figure, which is vastly different from how the villains of the story like Voldemort are portrayed. Through speech and behavior, Rowling differentiates the protagonists from the antagonists in her novels.
Examining the nature of evil in literature, we often find that it serves as a contrast to the good, helping to highlight the heroic qualities of the protagonists. From joyful heroes to malevolent villains, these characters embody the struggle between good and evil, providing the essence of narrative conflict that propels the story forward.
