Long is the way and hard, that out of hell leads up to light is a long and arduous road, and the sentence that you will see light as soon as you get out of hell is not Dante's, but Milton wrote in Paradise Lost that Dante only mentioned in the Divine Comedy that the soul who committed one of the seven deadly sins in front of him was punished at different levels on the mountain of purgatory, and after the expiration of the punishment, there is hope that the soul will rise to heaven and return to the embrace of God.
