The line itself is saying that killing someone will make sure they can't hurt you, since dead men don't bite. That makes Billy's character seem like he led a rough life which is what I would answer with. He is not jovial, because that means cheerful, and the line doesn't give indication that all of Billy's friends are dead or that he doesn't like to think of the future, so I'd say answer A.

Banning all alcoholic advertising might help to decrease underage drinking, but not necessarily. Many cases of underage drinking comes from peer pressure of other teens, some being older, as a way to get kids to "prove" themselves. Stopping commercials that advertise drinking may reduce the amount teens do it, because they see it less often and don't think about alcohol as much. This may also be a backfire because it becomes something less seen and there for more desirable for teen rebels to try. The best way to find middle ground is to keep these commercials on more adult based channels to avoid encouraging underage drinking.
