I just responded differently but on your point! Not as disagreement nor as a Devils Advocate which is a point I picked up from this third part of overall. Love those words actually and what a great concept that any choice is ours! Always believer in positive mindset ideas. Nonetheless my reply intended to bring thoughts of possibility that forces exist Universally outside our individual control that can influence human brain waves and human behavior. We also are very comfortable in thought that we will always evolve for the better. History seems to indicate this wasn't always true in past. How about the current? Could devolution forces also exist? Could these polar opposites be cyclical?
