Yeah, a walk will keep you occupied for a bit, but when you get back home you know things will be just as bad. Actually, you'll probably beat yourself up over the fact that your efforts didn't make you feel better at all - perhaps nothing will, right?
Go kill a vagrant, Brian. I'm sure you'll get a rush doing something so few have done, and the high you get from the conflict resolution of securing an appropriate disposal will tide you over for at least a month or two. Of course, after that time, you might just have to kill two. Or maybe just one, but the period in between is significantly shortened? I don't recall.
