You are right, they aren't smart enough to look from a species point of view. Each person on earth thinks they are the center of creation, so they shouldn't be the one to die. It's a biological problem, we all think we are the center of creation. Ma, doesn't believe that however. She is doing a moderatly good job of thinning the herd right now. As this pandemic continues, as I expect it will, for many years ahead, the herd will gradually be thinned some more. Ma is always right.
