I feel it's not about weather you kill or have killed but it is about how you carry yourself. If you are about your business and handel your shit, and be "you" despite what anyone says, you are gangsta, O'G's are the original killas, they are from the block and live that life forever, todays kids think that that way of life is cool so they join, but they are setting them selves up for faliure and struggle through out there lives. Off teh top of my head look at Luda, he has to my knowledge never killed anyone, yet many see him as a boss.
