Even though there's little chance that the Flower Children will have to go to war, some of them will experience or witness extremely violent, bloody, and terrifying events, such as in car accidents. They won't be able to take it. Their life as functional members of society will be over.
I know a former lawyer who had lost a case defending a drug gang. They tied him up and murdered his wife and child right in front of him. He lives in a world of his own, though he can enter reality from time to time if it is non-threatening. If he had experienced violence before the murders, he would have reacted sanely and become a prosecutor to get even with criminals, who are less human than pitbulls.
