Look at this
LOOK
I’ve never made this connection before…at the beginning of DH Hermione tells Ron and Harry how a wizard who’d split his soul could heal himself, save himself…remorse
oh, harry
Harry James you precious baby
I’ve read this second bit before, the whole try for some remorse thing, and thought it was just a Harry stabbing in the dark, but nO
It was so calculated
He remembered that conversation
Hermione’s research
actual, possible redemption for Voldemort
he kept that hope, however slim, that Voldemort could be saved
before they cast their final curses, after all that happened, Harry was actually trying to get Voldemort to mend himself back together
Harry james potter you compassionate jerk trying to save your mortal enemy before he utterly and finally destroys himself
HOLY SHIT WHAT
He had hope for his enemy, because he knew how alike they were, how similar their life had been, but knew that he himself had chosen to be good by virtue of self-reflection and guidance from those who would not allow him to lose himself. He tried to do that for his enemy. His enemy made his choice. Harry had done all he could. Harry reaffirmed his own character.
As much as Rowling borrowed, reorganized, and flat out stole from myth and fiction, she put it together very, very nicely.
