The Ending Of Sam Raimi’s Spider-Man 2 Explained

Otto Octavius is an excellently written villain, because he has both understandable motivations, and a genuine drive to do good. His original desires — to create renewable energy — are noble, and intended for the sake of benefitting the planet, even if they get twisted following his wife’s death. Much like Peter, he was trying to think of others instead of himself — because if we follow Uncle Ben’s teachings, having the means and power to help other people gives you a responsibility to do so. 

Then his inhibitor chip — which stops the A.I. in the arms from getting into his head — gets fried during the experiment, and he winds up committing robberies, and murdering people, to finish his experiment. There’s no question that he’s misguided, but it’s easy to see the parallels to Peter Parker, in that he becomes so determined to help the rest of the world that he doesn’t let anything get in his way, including Spider-Man (or the fact that his experiment, on both occasions, becomes wildly dangerous to the city at large). In Ock’s mind, even kidnapping Mary Jane is a necessary evil on the road to potential greatness. 

However, as the ending proves, the weight of Octavius’ ego doesn’t mean he’s incapable of owning his own mistakes. Spider-Man 2 is a film where the recurring theme is about the gifts we all have, and the responsibility that they come with: thus, in the final battle, as the reactor threatens New York City, Peter unmasks and repeats the advice Octavius gave him earlier in the film — that his intelligence is “a gift, not a privilege” to be used “for the good of mankind.” These words hit Octavius with a moment of clarity. The weight of his grief over his wife’s death has caused him to lose his way — much like Uncle Ben’s death nearly got the better of Peter in the first film — but he sees the error of his ways. So, by sacrificing himself to plunge the reactor into the water, he accepts that this was his problem to fix, taking full responsibility for his actions.
