A young man named Angel who is very skilled in combat and lives in a dangerous neighborhood decides to take matter into his own hands for the people he loves most with murder

A young man named Angel is not very descriptive, and a character's name should never be stated in the logline. Is he military? Homeless? Junkie? Police officer? Or a bank owner? Specify who he is; considering he is trained in combat, figure out a way to compile your first line into a couple of words of character description. The event is also missing: why does he decide to take matters into his own hands, and why is his neighbourhood dangerous? Why does he have to murder people for his loved ones?
