I am probably going to go against the majority here but here it is.
What if: Most (not all) actors are "white hats". What better way to wake the masses then have those that they watch and idealize show them by playing the bad guy. They are excellent at their craft and willing like a soldier to sacrifice their personal life to do so. Part of "You are watching a movie" perhaps, "sorry it had to be this way" "Some you think are good are bad, some you think are bad are good". "You can't tell them, you must SHOW them"
What better way to spy on Hollywood than to *infiltrate, how would you do that ?. Keeping an open mind, we will find out.
