He also uses the word “Debauchery” which is clearly defined in the Koran and other Islamic writings like

“Burkha Vs Bikini
The Debauchery Of American Womanhood”

I think the debauchery he mentions is the fact that this girl he liked was dropped off at her dorm by a guy at 7am. He was probably sexually frustrated on top of being paranoid and depressed and the fact that other students were getting some made him pretty self rightiously indignant.

Here is another clue that Cho was MUSLIM.
From the violent “play” written by Cho, “Richard McBeef”:

Others have focused on the brandishing of a chainsaw during a fight and the killing of the child character at the end.

But I found something more subtle on page 6

“(She peeks at John. She approaches Richard and slaps Richard in the head multiple times. TAKING OFF HER SHOES, SHE HITS HIM HARD.)” [emphasis mine]

Striking with the shoe is a Muslim sign of disdain represented by the dirt on the bottom of the shoes. Scenes filmed in Iraq have frequently shown people striking such things as toppled statues of Saddam and killed captives with the soles of shoes.
