From this and the rest of your statement, I seriously wonder how you chose the handle, "Joyful"
God knows exactly how we will react to any given situation, but we don't, so we have to experience it personally to understand later on why his way is perfect, to avoid God having another problem to deal with such as Satan, who was made perfect, but didn't understand what a blessing it was, and no one can, until they get to see both sides.
I disagree that without experiencing both sides you can not appreciate being perfect. The other angels were the same as Lucifer but the all did not rebel. Obviously they appreciated it.
Also, if we have to experience it personally it does not explain the purpose of those who do not go to heaven unless they are automatons without out free will controled by God to make us understand his way.
