What kind of people in prison will become better and turn over a new leaf in the future. In fact, the reason is very simple. What kind of people will get better in prison depends on how people change their wrong attitudes in prison and what they are in prison for. If it is out of principle or political problems, they will get better again. If they fight, commit hooliganism, murder and fraud, no matter how long they stay in prison, even for life. After they come out, they will not change the nature of the bad guys, so it is very important to say what kind of people will change and turn over a new leaf in prison, mainly depending on their personality and what mistakes they made in prison.
