Is it wrong to give someone legal advice when in the past you have helped people get out of jail wit the advice I gave them?

I have spent alot of time incarcerated and I studied alot of law. I got tired of seeing people get mistreated by the system and decided to do something about it. I started studying law and reading law books. I got pretty good because I started filing motions and appeals for people because I wanted to help someone. I actually got a few people out if jail on appeal. I still have people ask me for legal advice and I would really like to help them but I don’t know if it’s right but I know I can help them. What should I do?
