Over the years Peter had always been envious of Harry, they were best friends until he found out he was Spiderman. Only a couple years ago Peter... Well Spiderman killed Mr. Osborn, because he killed his Grandfather and almost killed the love of his life Mary Jane Watson. Peter wondered if this could be the "revenge" Harry had been talking about and contemplating. Harry had nothing now, no fortune, no Mary Jane and no best friend, he's life became a dark hole of nothing. All he cared about was destroying Spiderman for taking everything he ever had away from him, and maybe this was his way of doing it. On the way to Harry's place, Peter tried to talk himself out of confrontation and turn around, he tried to think it was pointless and Spiderman could just work things out with the public a different way, but that wasn't who Peter was and it definitely wasn't Spiderman at all. Spiderman wasn't afraid of anything, he wasn't scared of Harry or the Green Goblin, he was supposed to be an idol. If he wanted his name cleared then he was going to have to do it this way.
