When describing Klebold, I was shooting for a layman's description so I took the two traits people most often attributed to him. I will provide these links for people who want an in depth profile. The main point is that there were not two equal partners in the tragedy, Eric, the psychopath, was the main driver.
It is my understanding that, rather than idolizing, Eric wanted to outdo Timothy McVeigh. Beyond having a common interest in bombing, Eric did not share any philosophical views with any of the other bombers.
I was thinking more like they sympathized with Timothy McVeigh, Ramzi Yousef, and Ted Kaczynski and could not watch them in the Supermax Prison, which is not too far from Columbine. They probably could even relate to them since they saw them screwed by the government like them after they were arrested for breaking into a van in early 1998.
