It’s not. If you see the prey that is being attacked and escaped has no problem after a few seconds to go out and about and start grazing as if nothing happened. It has to do with our biology and big complex brain.
If you get attacked by a lion now, you will get PTSD or some kind of trauma, which will change your brain every so slightly; add more of those traumatic events and you have a depressed brain; add to that the life span humans have and the different mutations they inherit you have an overactive sympathetic system that can not calm down.
