Mao as an Example of What Happens to People When Ethics are Forced Upon them:
"I've done all my chores, so leave me alone.", a young Mao (from one of his biographicals, I can't recall which one).
This was an incident in Maos childhood when his father found him reading in the garden, and consequently berated him for his idleness. So called ethical laws are imposed on people without explaining the why of it. The consequence is that the child, or person, has no connection to truth. They are told to obey, but not told why its beneficial for them. Hence they develop animosity toward the laws, and become distanced from other people. This then leads to a drop in empathy, as the person has no connection to truth, and views people as constantly imposing laws on their for no reason other than their own whim. Thus Maos attitude towards other humans develops into one of indifference, borderline sociopathic, as his only interaction with people has been one of impositions on himself.
