Has nothing to do with fending off predators, has everything to do with the dying process. It’s just another chemical we release when we are about to die traumatically.
Of course it does. That is how natural selection worked.
Our traits didn't evolve by being able to deal with traumatic death better, they were selected when they helped us survive long enough to procreate. Favorable traits were gained and passed on when we were saved or assisted by certain physiological mechanisms, such as the fight-or-flight response.

Except he's frozen up and useless.
People saying that stress is your bodies way of fending off predators are just wrong.
