Professor Snape Bust (Harry Potter)

Severus Snape is a very unpleasant man. He uses his position as a senior teacher at Hogwarts to continually bully students he has taken a dislike to, and to blatantly favor his own house. Professor Snape is petty, vindictive, and able to bear grudges for enormous lengths of time. Yet on the other hand, Snape is a quite brilliant wizard and potion-maker, a tireless worker for the Order of the Phoenix in the cause against Voldemort at great risk to himself, and a man who is totally and unquestioningly trusted by Dumbledore, the greatest wizard of our time.
