It is my belief that Satan has a reason. I cannot prove what is scriptural, but by paying attention to the descriptions of the fiery red dragon mentioned in Revelations, "who accuses us day and night before our God" one is too quickly reminded of the Job. It seems very frightening to me and yet profoundly comforting in a way, the implications of Job. First off, I realize mentioning that comfort is not exactly an ideal word association with Job. But, the sorrows of Job led by 'The Watcher of Men' is not merely a display, but to the purpose of, that after Job triumph of suffering, no evil can touch him. I myself have not suffered much in my own life, and have not been just always, but I often think about righteousness, and it is to this end that I would say definitively that Job is the most intense and profound writing of religious text that I have ever come across. If this 'Watcher of Men' is Satan, then he himself admits the afflictions are for the purpose of becoming free of evil. But remember God for 'Both the deceived and the deceiver are His'.
I am in the process of studying Job. I might add more information are thoughts to this thread.
