Why do our brains release these ‘chemicals’ that make us not afraid in our last moments?

I’ve heard of people with near death experiences having these calm, soothing experiences. It’s lovely that our brains do this for us.
I know there’s a natural selection, those with the best characteristics continued, and those who didn’t have the qualities to survive would pass away. But everyone dies in the end. What made it so that all brains release those chemicals to ease our last moments?

We had received a kicker box of food at our patrol base in Afghanistan. I hadn’t eaten anything other than MREs in weeks. They had some chicken strips in the kicker box so we cooked them up. All of a sudden a rocket attack happens on our position. The potential end of life calmness let me finish my chicken strips so I could go out happy. Luckily the rockets ended up missing me. Not sure where that brain function comes from but it’s pretty nice.
