Evil, or Boring
All novels, all poetry, are built on the never-ending contest in ourselves of good and evil. Everyday we see people acting like good citizens. They aren't going out and building houses for starving orphans with AIDs, but they aren't going around causing mayhem either. So since they aren't doing anything wrong, we group them into the "good" category. Because, they could be doing something worse, right? We get used to people acting "good", and don't think too much of it. As a result of this uneven arrangement of what is considered good and evil, "evil" is rarely seen on a daily basis. Therefore it the often the target of over-exaggeration, and much more interesting stories. To most people evil is unfamiliar, and thus, exciting as hell.
One example of how good can go unnoticed can be found in most every high school. Just through gossip, I can tell you who the sluts, potheads, racists, and gay people are.
Not that I consider all or any of these people evil, but to most, these are the people to avoid. They are the ones your parents/church tells you to stay away from. I don't know any of these people personally, but I know more about them then I do most of my friends. But if you asked me to name more then 3 people who are not one of my close friends and who achieved a 4.0 GPA, are going to college, are taking JC classes, or have a job at the hospital, I would be unable to. I know more about the "evil" people, their lives are just more fun to know about.
The same one sided knowledge can be found in history. If you went up to a 6 year old and asked them...
