This is a character from Harry Potter who was one of the four Marauders and everyone hates him. His animagus form is a rat and he is a rat on the basis that he sold information on James and Lily and Harry Potter's hiding place to Voldemort in exchange for his own life. Then he, who we
hate, framed Sirius, who we love, for murdering
13 people and lived as a rat for the 12 years that Sirius was in the hell hole of Azkaban
prison. In conclusion, we
hate Peter, and Sirius never died in OotP.

parents but it was somebody who up until quite recently i belived to be dead."

Potter:
