Law school just won't do that for you. It's not going to give you that kind of contact with the people you want to help--victims rights advocates will get that, if you get a job as a prosecutor. If you want to help people, go into counseling. That will at least allow you to choose your clients and work with them directly to really help them. Working as an attorney isn't about the client or making things better, it's about solving problems strictly in a legal sense. Plumbers get more interaction with their clients than lawyers do.
