DON'T START IF YOU DON'T LIKE THE FINISH
The problem these days is that everybody wants respect and money. They expect to obtain respect and money through committing crimes and often knives are used in such crimes. They think if they stab someone they will gain respect, this sort of behavior does not go unnoticed by the law and may involve the public who may get injured trying to step in. Gangs often require its members to carry knives on the street and this calls into question the safety of others.
