If your definition of "good" is violence, anti-social behavior and living a hard life I suppose they are. If you want a real life, a family, respect and peace of mind though, a gang isn't the place to look for that.
you are so one sided when you answer these questions.because when you look up the definition of gang and not follow a steroetypical way.you will see a gang is a group of people.and its there choice what they do.
I'm taking into consideration previous comments the person asking the question has made about the Crips and the Bloods.
"The Crips are one of the largest and most violent associations of street gangs in the United States, with an estimated 30,000 to 35,000 members. The gang is known to be involved in murders, robberies, and drug dealing, among many other criminal pursuits. The gang is known for its gang members' use of the color blue in their clothing. However, this practice has waned due to police crackdowns on gang members."

Chanel_swagga: Maybe gangs are different in the UK, but what you're describing has no basis in reality in the US where guns are all over the streets. Sorry, but your comments just aren't making sense in our social context. We're not talking about the Boy Scouts or a book club.
Gangs may differ from one place to the next. Like skyDancer said, we both don't know what gangs are like in the UK. In the US however, guns are everywhere. Constant gang banging. Killers. Drug dealers. Sex. Gang deals. Ect. Gangs also vary and differ.
