Black Spidey

Is it possible for us to be a good person alwayS and always go correctly as per the books ? Do we have it in us to be good always ? Hey most of us are good at heart , but sometimes being too good can lead to a downfall and end up having people treading over you. You become weak. Sometimes after being good for many years , and when you see all the bad people are doing well ,we tend to doubt , whether all our goodness was worth it ? After many years of being good , we may slowly slip for a moment towards our darker side for a while. Just like in the movie Spiderman 3 , where there is this 'good Spidey' and the 'bad Spidey'. Its not that spiderman was a bad person , but he too has his black sides despite being a superhero that saves people. But at the end of the Spidey story , the good overcomes the bad , and everyone is happy. I guess each one of us have black sides just as Spidey did. Yeah , we are all good people , its all about taming the black side. If we didnt have a black side ,perhaps we are not human. I guess its ok to be black Spidey for a short span , but we must make sure we return to our good selves at the end.
