And as you've perfectly mentioned, Norman's an even better Spider-Man villain dead. The spectre of Norman Osborn is greater than Norman Osborn. It allowed his character to become something so much more. It allowd his son to become a far more compelling Green Goblin. Norman's Goblin sucked. Harry is beautifully twisted. At his true core, he knows that his father killed his dear friend Gwen Stacy. He knows this! But his inner child, still yearning for his father's love, makes the man act childish. He blames Peter for everything, and by extension Spider-Man. Harry is insane. Far more than his father ever was. After Peter comes out of his drug induced hallucination, Harry asks him if he's ok. If they need to talk. It's wild. Peter still wacked out, beats the hell out of him and takes off. But Harry is so conflicted. Right up to his tragic death. He planned on killing himself and Peter and then he saves Peter at the last second. Why? Because he loved Peter and hated his father.
Other threads have been dedicated to discussing whether or not Norman should have been resurrected. I'm asking why was Harry resurrected. His story ended. It was told. Future writers can really only tell it again the same exact way or keep him Peter's best friend (boring!!!).
Isn't Harry destined to become the Green Goblin again?
Isn't that what everyone is waiting for?
Problem is, for us guys we've already seen that story done perfectly. Harry should have remained dead.
