Peter Parker spent 50 years fighting crime with little money or support. Parker fought for all New Yorkers, even the ones who tried to ruin him (ex. Jonah Jameson, Harry Osborn). Selflessness was his greatest attribute. How many times did Spider-Man's foes try to break him? The Goblin stories alone would have felled a lesser hero. No, Spider-Man fought, inspired, and served his fellow person time and again.
Could anyone see Doctor Octopus doing the same? Isn't this move a good thing? Walking Spider-Man's first* archnemesis through his life, teaching him the value of heroism and humility? A selfish person couldn't do what Spider-Man does everyday. "Superior Spider-Man" is ironic for a reason.
*Doctor Octopus was Peter's most formidable foe before the Green Goblin, no?
