The number 9 is the "most evil" number in the occult, and killing is the most evil thing a human being is capable of.

IX + NINE + NINE = 999 ↔ 666

THE NUMBER 9 Aleister Crowley and W.W. Wescott both agree that 9 is the "Most Evil" number, the number of Earth under evil influences. It also invokes deities of supreme importance to the occultists.

Thus, the Crowleyian formulation—9, “Most Evil,” 11, “the magic force itself ”—yields: 9/11 = Evil Magic. Not simply numerical shorthand for the day or its proceedings, but communicating the nature of the event itself, a digital combination whose very meaning is “Evil Magic.” The untold number of times that the phrase “nine eleven” has been spoken or written in the past ten plus years…that it has appeared in print or on screen, been uttered on the airwaves in news reports and documentaries, been said by countless millions in private conversation—every time it is used, we unknowingly participate in the MegaRitual, repeating “Evil Magic” over and over.

The date 9/11 as also had astrological importance - at that time Saturn was in opposition to Pluto, both of whom are the Gods of Death (Pluto being the planet of "death/rebirth/transformation").
