Maybe JK Rowling has some plan for Harry to be broken or changed in some way, if the meaning behind his life is broken, his friends or loved one dies and he cannot save them, this may change Harry in the same way as Annakin Skywalker was, Frodo managed to save the Shire yet he was still broken in some way, how would he have reacted if he'd had real power and seen the Shire being destroyed in front of him, would he have used absolute power for good knowing that the same power may corrupt if used by one with unbalanced emotions. Maybe in using that power Harry is seduced by The Other side and kills one of his friends only to be saved at the last minute by the awful realisation of what he has done, or by the appearence of his parents, in this he would be similar to Frodo's temptation by The Ring, and Gollum's intervention.
