Simply put, Peter Parker was a nerd...a science geek. He was doing a science experiment and was bitten by a dying, irradiated spider. This would be why we don’t allow live animals in science fair experiments. This dying spider imbued Parker with spider-like tendencies, and (according to the movie) his aunt made him a Spider-Man costume.
Okay, so here's the point of this: Spider-Man and Peter Parker are "do good anyway" kinds of guys. In school, Peter Parker was ridiculed for being a good student; he didn’t stop being a good student because of that, he just kept on. Later on, as a photographer for a newspaper, his boss (the editor of the paper) hated Spider-Man and made him out to be some kind of freak villain; Spider-Man just kept saving people.
No fuss. No production. No shame. He just kept on doing good anyway. Oh, he got confused a few times (they had to have something to make three movies’ worth), and he made some poor decisions. But, on the whole, he did good anyway.
None of us is Spider-Man--although I still see quite a few during trick-or-treat time. But we all have had people make fun of us for something we did--even though our motives were pure and good--we were accused of grandstanding. Most of us likely have just gone ahead and done the right thing. We’ve done good anyway.
