The cruelty of criminal cases in real life may be more real and common than in novels. Criminal acts may cause physical and psychological trauma and pain to the victim, such as kidnapping, abuse, murder, rape, etc. These acts were usually carried out through cruel means such as beheading, organ cutting, torture, etc. These methods not only caused physical harm but also caused great trauma to the soul. Cruel acts in criminal cases may also be related to social background, personal personality, and motives for criminal acts. For example, some people might feel proud or satisfied because of their criminal behavior or because they think they can change the fate of the victim. These factors may have increased the cruelty of the crime, making the case even more shocking and incomprehensible. Although the cruelty of criminal cases may be more real and common than in novels, the law and law enforcement agencies have always worked hard to ensure that victims receive fair trials and treatment while protecting the safety and order of society.
