In Lolita, we read the beautiful prose of a serial child rapist. Humbert's actions are unforgivable, yet we were given the opportunity to hear his side of the story and at least gain a little bit of understanding of his motives. Humbert was a player in the game of love, it was just unfortunate that his particular brand of love is deemed sinful by most societal standards. Can we really blame him for this?
In Blue Velvet, Dorothy is viewed as a mysterious, dark woman by the whole neighborhood. It isn't until Jeffrey delves into her personal world that we find out about her very real and very serious problems. We see that she isn't just a weird, scary woman, and Jeffrey sees it also. This also leads us to see that Jeffrey isn't just an innocent suburban boy. Things are never what they seem on the surface.
Jimmy McNulty in The Wire is supposed to be the "good cop", and in most cop shows we would probably only see that side of him. However, The Wire does a great job of showing us that McNulty is indeed playing his own games. He is in the middle of a divorce because he cheated on his wife, and he is all about getting some personal recognition. The Wire also shows us that not all of the "bad guys" are completely bad. Omar may be a murderer, but he always obeys his own rules, and we even see a softer side of Wee Bey, who seems to be, in my opinion, the most unfeeling character on the show.
Overall, it is important to remember that every story always has more than one side. Everyone always has his or her own battles to fight and games to play. If anything could ever be "fair", you'd have to look at all situations from every possible angle. This can never be, but perhaps I'll always have that idea in the back of my head.
