Seems obvious that these are not good role models. The fact that a man-child can be celebrated for calling himself "C-Murda" shows:

1. His community has terrible standards for behavior and are firmly rooted in celebrating the criminal element within
2. People who are supposed to be serious have become blind to basic standards of decency in entertainment, media, and personnel, e.g. ESPN

The idea that celebrating "murda" with one's choice of "street name" is equated with "being black" or a "black thing" is something that should offend more black people, unless they forever want to be associated with criminality.
