"There are two contradictory views of Eric Harris. One is that he was an ostracized, lonely boy who was tormented by peers into an act of retaliatory violence. The alternate view is that he was essentially an evil monster. This is a pejorative label, however, not an explanation. To understand Eric, we need to go beyond labels to the internal workings of his mind. When we do so, we find that both views- the mistreated loner and the evil monster- are inadequate. The view of Eric as a lonely victim of harassment is not only inadequate but, to a significant extent, inaccurate... Eric was not a loner. He had lived in Colorado through middle school and high school, had multiple groups of friends and engaged in a wide variety of activities with his peers. He lived a highly social life and was liked by both boys and girls. On April 9, 1999, just 11 days before the attack, a group of Eric's friends took him out to dinner to celebrate his eighteenth birthday. But he was teased, wasn't he? Yes, he was. But so were many other kids at Columbine, not to mention everywhere else. And bullying? Having read thousands of pages of interview reports from nearly every student at Columbine High School, I found only one report of an incident in which Eric was physically harassed, and this consisted of being pushed into lockers."
