This can be easily said about spirituality as well. Anecdotally, I've met far more people with higher density narcissistic traits who cover their behavior with beliefs, enlightenment, and morality than I have of those with trippers. Unlike you, I don't think spirituality is a poison pill as a result. Instead I think of it as something that must be constantly measured, dosed, and negotiated with depending on the outcomes for a particular person. This is similar to how I think of psychedelics.
