Professor Snape - A professor of Potions at Hogwarts. Severus Snape dislikes Harry and appears to be an evil man for most of the story. His name associates him not only with unfair snap judgments of others but also with his violent intentions to snap the bones of his enemies. Snape’s grudge against Harry, which is nevertheless far from a murderous ill will, helps us remember the difference between forgivable vices and unforgivable evil intentions.
