Meals on Wheels Angel murdered Brooklyn

What would be a motive?  I have a theory?  People attempt to destroy what makes them feel inadequate.   Murdering someone, trash talking them, putting them down, lieing about someone is to a drug addict cocaine -- it is a momentary escape from the pain of self hatred.   

This guy was a saint and part of the amazing mosaic of people here in NYC that make a difference.
