Why do adults encourage kids to eat chocolate candies at Halloween in US?

some where along the way a large part of the world has decided that we should live in protective bubbles being careful not to do anything that may be in some form or fashion "harmful". life is made of more than health, life is also made of a good overdose of chocolate when you're 10...a scary movie that maybe doesn't have a moral to it...sniffing a flower that might give you hayfever....i would take 60 years of limited use of the deadly chocolate as opposed to 90 years living in dread and fear in perfect health. i think it is unhealthy to shield a child from the natural enjoyment of life..
