God let everything that happens happen because he gives everyone free choice... and he gave Satan free choice... Satan is the biggest deceiver of all time... and he deceived Angels to believe that he could be greater than God... God didn't give him any special powers that would benifit him from other Angels in that sense... besides deception... And the reason why everything isn't so perfect and divine.. is because that is heaven... that is the whole reason why christians do what they do... they want to get to a place perfect and divine. And the G.I. Joe's thing was just an example for lack of a better one.
