Harry Potter and the Half-Blood Prince
How we cite our quotes:
"If Voldemort had never murdered your father, would he have imparted in you a furious desire for revenge?" (23.150)
We think the answer to this question is most likely a resounding, no. Yes, Harry's quest to kill Voldemort is a personal one. But we also know that Harry understands the threat that Voldemort poses to humanity. Beyond the Dursleys, Harry has no blood relatives left, and so revenge perhaps comes more easily to him than it would to others.
"Voldemort himself created his worst enemy, just as tyrants do everywhere! Have you any idea how much tyrants fear the people they oppress? All of them realize that, one day, amongst their many victims, there is sure to be one who rises against them and strikes back! Voldemort is no different." (23.150)
Here is an interesting moment that causes us to put the story on hold and turn on the History Channel. Can you think of any other tyrants in history or literature that fit Dumbledore's description? What were these tyrants' childhoods like and what kind of power were they seeking? It would seem that Voldemort's desire for isolation and power might be his greatest weakness.
