"...everyone should be put to a test. an Ultimate Doom test. see who (unreadable) an environment using only smarts and military skills... Put them in a Doom world, no authority, no refuge, no BS copout excuses. If you can't figure out the area of a triangle or what (unreadable) means, you die! If you can't take down a demon w/a chainsaw or a hell prince w/a shotgun, you die!"

In August, 1998 Harris wrote out a list of "25 Things that make me different." Number one was:

"My love for a computer game called Doom. Doom is such a big part of my life and no one I know can recreate environments in Doom as good as me. I know almost anything there is to know about that game, so I believe that separates me from the rest of the world... Doom is so burned into my head my thoughts usually have something to do with the game... the fact is I love that game and if others tell me, "hey it's just a game" I say "hey, I don't care"

"It'll be like the LA riots, the Oklahoma bombing, WWII, Vietnam, Duke and Doom all mixed together," wrote Harris in reference to the planned incident. "I want to leave a lasting impression on the world." Other subjects represented in the materials include Nazism, torture, music, and belittlement at school.
