We cannot generalize that people who have committed crimes will never completely change their bad habits. Many people who have committed crimes have been able to deeply realize their mistakes, sincerely repent and work hard to reform themselves after serving their sentences, undergoing education and reform, and self-reflection. They have successfully bid farewell to their past bad behavior patterns by actively learning skills, cultivating good morals and behavioral habits, and rebuilding interpersonal relationships, and have integrated into normal social life and become people who are beneficial to society. Of course, it is true that some people may find it difficult to completely abandon bad habits, but the situation of these people cannot be generalized to all groups with a criminal history. Society should give opportunities and support to former criminals who are willing to reform, and help them get on the right track, rather than holding prejudices and stereotypes.
