The Nature of Heaven

I wonder if free will is one of the explanations or perhaps the explanation, at least of moral evil. The reason why God allows people to commit evil is because free will necessitates their ability to do so. Do you think that there is free will in heaven? Not free will to choose between good and evil now, but free will to choice between many different good states. Heaven best regarded not as a reward for being good, but as the place where good people would be happy. It's an actual home for them Because the occupations of heaven worshiping God are those sort of things bad people wouldn't want to do. Gradually it can make us saints unsuitable for heaven.
