I think you are good guy and your friend is lucky to have you in his life. I only say try not to enable him to not work for himself, and don't let him interfere with your life or stop you from your own dreams and goals and what not. Ive heard fights start over less, "A meatball sub" for instance, or a person "looked at me wrong", or one time I saw a fight break out in a pizza place and still don't know what caused it, but it was brutal. Like a real live fist fight, scary. There was blood and some pretty bad contact made. Maybe they were f over a soda or a girl, who knows. But, yeah, so, it probably is in your best interest to keep your friend around and out of gangs and such. At some time in your life, you may be glad that you did.
