My mom has paranoid schizophrentia and she seems alot nicer now than before she was diagnosed.Not long after she was diagnosed she went in and out the mental hospital several times because she thought she didnt need the medicine anymore.When she got off her medicine she didnt hurt anyone. She just got to where she would stay in her bed 24/7. She wouldnt even get up to take a bath or use the bathroom.Now at times she would be riding with me to the store and if she saw a cop she would tell me that i was trying to turn her in and make me turn around and bring her home.But she never was and is not a danger to society.It has been 10 years since she was diagnosed, and she has been taking her medicine every day for like 7 or 8 years.She is just like a normal person.She can drive herself pretty much everywhere and she can pretty much do everything she use to before she was diagnosed.So no i dont think they are a danger to the society.
