Throughout the Harry Potter series, the Dursleys treat Harry very cruelly in regards to his magic. How does fear drive their actions? How does fear control us, and why might it be hard to be tolerant of others when afraid?
The Dursleys treat Harry very cruelly in regards to his magic because they blame it for the death of his parents. Both, including Petunia Dursleys' younger sister Lily, were killed by Voldemort as young adults when Harry was just a baby. Fear can control us and make it hard to be tolerant of others because we believe certain kinds of people will bring pain or death.
