That was a really amazing story! Society builds a "no giving wall" because they don't understand what they never experience and it scares them so they wont learn what it means to give and help someone in a situation they them self could be in. You acted on that inside voice despite what others may think and you will learn and become a better grounded person because of the experience and knowledge that you gain from that one action. That is a very hard wall to get past. It doesn't matter what that man did with the money because you still provided him with the chance to change with a good intention. It really wasn't about the money but the act it self, that is love in a time when he had none, when he was alone in this world with nothing and no one to care about him. Don't change who you are, ever.
