To all you budding Solipsists out there, I want to make you aware of the danger you may face in case of:
 an emergency like a a plane crash, a natural
disaster that disrupts all logistical systems, a riot;
 a state of total war, probably nuclear, in which all
social structures and institutions were destroyed;
 your imprisonment whether innocent or not in
many State and most Federal penitentiaries.
You would immediately become aware that, under these circumstances, many people would subscribe to your Moral System. You would confront a terrifying Hobbesian nightmare where, to your paralyzing dismay, you were the prey in the middle of a circle of relentlessly advancing human predators, whose prior socialization enabled them to see the advantage, as wild dogs do, of hunting in packs.
