Harry Potter and the Half-Blood Prince
How we cite our quotes:
Harry was left to ponder in silence the depths to which girls would sink to get revenge. (15.102)
Well, now, Harry, not all girls are full of revenge. Isn't Harry the one trying to go about incriminating Malfoy? Hey, wait a minute, doesn't Ron show signs of inflicting revenge on Hermione after he finds out she went on a date with Cormac? Hmm… your theory is being tested, Mr. Potter.
"No, I did not. Though he had shown no hint of remorse, it was possible that he felt sorry for how he had behaved before and was resolved to turn over a fresh leaf. I chose to give him that chance." (17.112)
Dumbledore has always hoped and continues to hope for the best in people, regardless of their track record. When Voldemort returns to Hogwarts ten years after his graduation, asking for a job, Dumbledore wants to believe that he has had a change of heart. This hopefulness and willingness to believe in the good of people is what makes Dumbledore both powerful and vulnerable. And yet, we feel comforted that someone as important as he is would have this philosophy.
"Voldemort Stupefied his uncle, took his wand, and proceeded across the valley to 'the big house over the way.' There he murdered the Muggle man who had abandoned his witch mother, and, for good measure, his Muggle grandparents, thus obliterating the last of the unworthy Riddle line and revenging himself upon the father who never wanted him. Then he returned to the Gaunt hovel, performed the complex bit of magic that would implant a false memory in his uncle's mind, laid Morfin's wand beside its unconscious owner, pocketed the ancient ring he wore, and departed." (17.156)
Here we not only get a glimpse of Voldemort's greatest and most personal act of revenge, but we also see a lack of loyalty to his own Gaunt family – pureblood wizards. He doesn't want anything to do with anybody. He flies solo. What other acts of revenge, if any, do we see Voldemort execute? What does this act of revenge tell us about who he is and what he is capable of?
