At the end of that movie, MJ was coming home with him, but he decided he's joined the super-priesthood and ghosts her and decides that being selfless is the way to go...and then in the second movie he goes backsies and guilt-trips her with mixed signals right through the movie making her justifiably fed up with him, and then he loses his powers because repression is bad. Then after seeing how crime has risen when he can't be Spider-Man anymore, what brings him back is Octopus kidnapping her by throwing a car into a cafe, and not the randos who he passed by in the "Raindrops are falling..." montage.
I don't know how you can look at that and say he behaves selflessly. That's totally the opposite of ASM#50 where it was stopping a random old guy from being mugged that brought him into action.
