Deranged Psychopath's rantings likened to Wicca

Mental State of Soldier Questioned

If I don't know where to start on this horrifying mess:

...A Fort Carson soldier and war veteran charged in the murder and sexual assault of a woman in Colorado last month faces accusations that he also raped a 14-year-old girl and sexually assaulted a third woman, an internal Army document states...

It seems that everybody who know this guy was certain he was completely deranged:

...It was common knowledge among his commanding officers and fellow soldiers, the document states, that Specialist Marko, who is being held without bond, believed he was an “alien dinosaur-like creature, and that he would transform from his human form into his Black Raptor form on his 21st birthday — 13 Oct 08...”

Yes, you read that right. He believed he was about to morph into a "Black Raptor", some type of viscous dinosaur, ready to prey on humans. But here comes the punchline in this horrendous story:

"...After joining the Army, his “unusual beliefs” in his Black Raptor alter-ego resulted in his being referred for psychiatric evaluations three times. Ultimately, the beliefs came to be viewed by his mental health evaluators as a religion, of sorts, like Wicca...“...His chain of command all shared concern over his mental state,” the document said. Their understanding from his evaluations...was that “Marko’s delusions represented an alternative belief structure — the equivalent of Wicca or some other alternative religion...”

Yup. That's just like Wicca. You read a Scott Cunningham book, light a candle or two, cast a few circles. Next thing, you're a psychopathic rampaging monster. I think the definition of "spirituality" and "religion" the services must be using needs some work. I just want to know on what planet would it be determined safe to put a gun in this sick person's hands?
