Did the characters in novels have to have flaws to be realistic?

The characters in the novel didn't need to be perfect to feel real. On the contrary, they should have some shortcomings and weaknesses that allow readers to get closer to them and better understand their personalities and emotions. Weakness could make the characters more three-dimensional and real, so that the readers could empathize with them more. For example, a character might get into trouble because of his own mistakes or decisions, or have some bad habits or habits, which can help readers better understand their character and psychology. Weakness can also enhance the realism of the novel because the actions and decisions of the characters are often determined by their inner thoughts and emotions. If the characters had no flaws, then their actions and decisions would lack realism and humanity. Therefore, the shortcomings of the characters in the novel did not need to be too obvious or prominent. Instead, they should be determined according to the plot and the characteristics of the characters. The important thing is to let the characters have flaws and let the readers understand and accept their flaws so that they can better understand their character and emotions.
