Victor, you are definitely in my prayers. I think that prayer is the best defense for now. Your brother has to come to the decision to leave the gang lifestyle on his own. The more you tell him that it is wrong or bad, the more he will want to stay with it. Just being there for him, telling him that you love him, no matter what, is best. He knows that you don’t approve of his lifestyle, so don’t hammer it in. God will take care of him, just be ready for when God decides to smack him ‘up side the head.’
