Personally, I think it's not good to expose people's ugliness. I think works that can fully embody human nature are good. We can't take a one-sided view of human nature and fall into a black-and-white situation.
Take four classic novels as examples. I don't think these novels reveal the ugly side of people. It should be said that the author objectively described a story, but the author did not express his views in his works.
Notre Dame de Paris celebrates a beautiful and romantic love. Quasimodo, the ugly hunchback bell ringer, and Esmeralda, the beautiful girl, have a sharp contrast between beauty and ugliness, resulting in the purest and most sincere love. In order to avenge his beloved girl Esmeralda, quasimodo also pushed Bishop Claude, who regarded him as the pillar of his faith, off the clock tower. All the stories revolve around love, about the girl's wrong heart, about the past and depth of the bell ringer.
There is no doubt that love is always the most touching of all factors. It is through expressing this pure feeling that more such as religious hypocrisy and collusion of interests are exposed.
Although the name of Les Miserables has the word "miserable", it is actually about the brilliance of human nature. From a tiny point, I found that he had covered everything. The life represented by various characters in Generate is full of pure power, such as Jean Valjean, Javert, Fantine and Cosette. They are all looking for hope in tragic circumstances and finally getting light.
Human nature is pure and kind, and they will go to happiness together, but they will go through a painful process. Compared with the tragic beauty in Romance of Notre Dame de Paris, the realistic work Les Miserables, which is similar to the lofty spirit endowed by ancient Greek tragedies, is more likely to arouse people's voices. After all, people have to live in reality after all.
