i think it would detract from the story, actually. the appealing thing about heroes is that they are basically like us - regular people with regular lives - who get put into extrordinary situations and, though they're like us, react in a way that most of us wouldn't. such as: peter's life sucks a lot; every time he gets close to anyone they end up in massive danger, his best friend wants his girlfriend but hates his alter-ego, etc. he gives up, but can't face himself afterward. he's a super-hero, not an emo-kid. he can be emotional, but only if he's eventually heroic. otherwise we'd feel gyped and lied to.
