What was the difference between a sad text and a sadistic text?

Sad writing and sadistic writing were two common concepts in web novels. The main difference between them was the intensity of emotional expression and the difference in emotional effects. Sad prose was usually a kind of sad, negative, and lost emotional expression, emphasizing that the protagonist had experienced misfortune or pain. It often showed the protagonist's loneliness, helplessness, despair, and other emotions. At the same time, it was often accompanied by helplessness towards fate and dissatisfaction with the world. The emotional expression of a sad article was often more profound. The readers would also feel sympathetic and have a sad emotional experience during the reading process. On the other hand, sadism was a more intense, extreme, and distorted emotional expression, emphasizing that the tragic experience and the fate of being hurt were often accompanied by the pain and struggle of the protagonist, as well as the emotional experience of the reader's sympathy, pity, support, and abuse towards the protagonist. The emotional expressions of sadistic novels were often more extreme and distorted. They often involved sex, violence, abuse, and other content that violated social ethics and laws. The readers would also have a stronger emotional reaction during the reading process. Sad and sadistic novels were common expressions of emotions in online novels. The main difference between them was the intensity of emotional expression, emotional effect, and content form.
