One for Sorrow

It's true that Harry has got to depend on his feelings-- and his friends, I'd guess-- to see him through, though I don't think he'll wind up actually rending his soul and 'killing' Voldy (I suspect there's a loophole in there somewhere, plotwise). Voldy has to die, in other words, but I'm not sure Harry has to murder him-- though this isn't arguable at this point either way, of course. It's also true that there's a lot more moral grey areas introduced in HBP, like with the goblet in the cave & Snape's whole history throughout the books, probably-- Dumbly has always been going about doing bad/questionable things in the service of the Good (perhaps a little too prolifically in his case). Harry, though, will probably always be a lot more straight-and-narrow about things than Dumbledore, but he may bend more than he's done in the past (one hopes). He's got to learn to see the shades of grey, to forgive-- hopefully even Snape, ideally Voldemort. Forgiveness of wrongs to self and one's beloveds-- that's what I sincerely hope Harry's got in the end, what distinguishes him as a 'true Gryffindor', what would allow him to win, for forgiveness is based in a form of love, that power that Voldy knows not of.
