Well, it really depends on the specific manga. Some might explore the idea, but many present a more nuanced view where evil is a result of circumstances and choices rather than an inherent trait at birth.
Well, I think it depends. Sometimes the portrayal of ghosts in manhwa is so imaginative that it's hard to take it seriously. But in some cases, they can add an element of mystery and excitement. So, I'm kind of on the fence about believing in them.
In my opinion, there are elements in Chapter 6 that could be interpreted as fate, but it's not a straightforward conclusion. There are multiple factors at work that might influence one's belief.
Believing in fate was a controversial topic. Some people believed in the arrangement of fate and believed that everything they experienced in life was arranged by the heavens. Whether it was luck or misfortune, it was all predestined. They believed that fate could not be changed and could only accept the arrangement of fate. Others did not believe in fate. They believed that one's fate was controlled by oneself. As long as one worked hard to change it, one could change their fate. They believed that fate was just a way of thinking. Through different perspectives and actions, one could influence one's own fate. Therefore, believing in fate still depended on one's beliefs and ideas.
