Harry thinking of Draco as a tool/victim (ch 9 of Deathly Hallows):
Harry pitying Draco and holding no animosity toward him for Dumbledoreâs death (ch 30 of Half-Blood Prince):
I canât really get this in a handy screenshot, but the entirety of the Sectumsempra incident lends a show of compassion from Harry toward Draco. Seems contradictory given what happened, I know. But, consider: Harry has been stalking Draco for months. He has a strong feeling that Draco is up to something, and he now has concrete confirmation. He hears Draco confirm that he needs to do his task, or else Voldemort is going to kill him and his family.
Harry leaves Draco alone after this. His concern is not with the person or people that Draco might harm. Itâs with Draco. He sides with Draco.
I also canât screenshot the entire Astronomy tower scene, but what was Harry feeling the entire time Draco and Dumbledore were talking? We actually donât know! In the course of the conversation, Harry states he hears a yell from further down the castle. He struggles against the Freezing Charm cast on him. He states he saw Dracoâs wand lower a fraction.
His thoughts and feelings are not shared until after Snape kills Dumbledore. Harry comes back to life. His focus is on Snape. Harry tries twice to use the Cruciatus Curse on him, and ultimately Sectumsempra.
And then, after everything has settled after Dumbledoreâs death, we get the screenshots above. All of Harryâs hatred is on Snape, and heâs worried about Draco and what else Voldemort might make him do.
Harry doesnât blame Draco for any of it in canon. Ever. He worries about Draco. Heâs sickened at what heâs seen of Draco being used for Voldemortâs amusement and ends.
As for that final scene, where Draco is pleading with a Death Eater (ch 32 of Deathly Hallows):
Again, zero thoughts from Harry. He puts down the Death Eater that was bothering Draco. Draco is pleading. Heâs happy when that Death Eater goes down. Heâs looking around for his saviour. They, proven by their actions, are on the same side in this moment.
There is no frustration with Draco. Harry gets it. He gets Draco, because he knows what it feels like to be a tool in an old manâs war (Dumbledore vs Voldemort). He knows what it looks like for someone to be used. He knows what it looks like when a boyâs anger and weak points are exploited to manipulate him into making horrible mistakes (Sirius in the Department of Mysteries vs Dracoâs 6th year task).
Harry understands. He knows what his purpose in the war is. Heâs prepared for it. He sees that Draco has been groomed into the same role, and is not prepared for it. He doesnât want it.
Thatâs empathy. Harry pities Draco and sees him as a victim the same way he pities himself and sees himself as a victim. Lest we forget (ch 16 of Deathly Hallows):
Harry wasnât exactly having a good time either. He recognizes this with Draco. Across all that space and time that separates them for the final instalment of the series, they transition out of bullying, squabbling, snarking rivalry to this.
Does Harry see Draco as a victim post-HBP? Yep. Post-DH, though? Highly doubtful. By that point, Harry sees in Draco his fellow survivor. They (symbolically) defeated Voldemort together, Harry using Dracoâs wand! How could everything else be anything but moot at that point?
Maybe people donât agree with Harry, but Harry is done with all of that. It builds for a while. Until (ch 36 of Deathly Hallows):
The Malfoys as a whole, not just Draco, get mentioned by Harry no differently than anyone else on âhisâ side. Whereâs the anger?
More importantly, whereâs it being read from?
