In the above mentioned scenario, I would alert the authorities, and probably try to avoid direct contact with an individual who is clearly dangerous.

When someone clearly has a problem, it's probably advisable to handle the situation with extreme delicacy, and most likely to bring in professional help.

I'm not sure what this question has to do with the issue of religious tolerance, unless you're trying to display your own intolerance by conflating seriously mentally ill persons with ordinary religious believers.

I certainly hope that you're not dealing with actual mentally ill, delusional people by glibly informing them that they "need help". If you are, then you might want to look into your own mental status.
