[Glenn E. Meyer]

Everyone's world view and decision processes are individualistic.

If your mental model is dichotomous, that's your brain. If one takes into account the probabilities of an outcome for a continuum of risk, that's your brain.

So if you in the store and a gun is drawn, you evaluate that you are in fear of your life.

If you are in the street and see a gun is in play as they enter the store, you might easily avoid. The guys might come out of the store and run after you. So do you want to enter the store and tackle them? Got to police society as a good guy!

If you are willing to die because your personal supernatural entity will take care of you, that's another part of your discriminant analysis regression equation. Perhaps it is the case that your family will be delighted with you moving off this mortal goal and getting your insurance and retirement funds. That's your business.
