How to dramatize violence and death

We've seen variety ways of dramatizing violence and death since the last unit. Violence is related to crime (Hery Hills' story, mass gun shot murders), game (the Hunger Game), or war. The stories can be either fictions or documentaries. Violence is dark but it can be entertaining if it is outside of our real world (like video games and the Hunger Game). However, due to its physicality, the violence is mostly associated with its back ground, such as poverty, hunger, and hostility. Why does the war create such a mess? I think it is because of systematic involvement (countries and countries, people and people) and long term sufferer. The war involves too many people for relatively a long period. all factors (poverty, hunger, hostility) are included and these factors exacerbate each other during the war. In the early 20 century, the people were involved in the war almost for a half century since the WWI. The situation made the people crazier and darker. Calvino dramatizes the detail and expresses the violence as if he experienced it (or observed) by himself, or more than that. In "Mine Field", at the end of the scene, mine's explosion is described as "Sun" so as the readers imagine its flash and and the readers imagine the body flipped around into the air. In "Going to Headquarters", the readers can imagine the decayed corpse with his expression, "black with ants". This is more than the fact (gun shot in crime, video games) and it is almost an art. Long term oppression typically leads the people to the art. Rome, Open City, depicts intrigues involving the German generals, Italian rebellion, women and men. The main theme is about the Fascism (supported by the Nazi) and the rebellion. It is interesting to think about how the movie was made at the end of the WWII. I wouldn't be surprised if the movie was made after the WWII (like 60's or 70's). But it was actually made just within the war. I am wondering if the movie could be recognized as an art at that time. Catholic church represents 17 century's  art. The scenes where the priest prays for the lord and the kids are gathering the church show up between the violence and the violence in the film. If the movie implied an political argument, the directors and the casts might be tortured at that time. It is reasonable to think of this film as an art. Both Calvino's book and Rome, Open City dramatize the war as a part of the new arts.
