Where in the story did it say he was 'ranting and raving'?
Again, being sick in the head and having a psychotic episode with religious themes doesn't prove that the person was 'deeply religious'. Point being, having a religious obsession simply isn't the same as a person being 'deeply religious'.
He may have been 'deeply religious' or he may not have been. The media doesn't really address that particular point to any degree for the simple reason its really not pertinent to the case.
And as of today they are adding animal cruelty charges as well.
