One reason could be to create a sense of shock or surprise. It makes the story more unpredictable. For example, in 'Game of Thrones', the sudden death of Ned Stark shocked readers and viewers alike, completely changing the direction of the story.
Sometimes it's to develop other characters. When a character is killed off, it can force the remaining characters to grow, adapt, or face their fears. In a detective novel, the death of a partner might make the detective more determined to solve the case and also show their vulnerability.
One reason could be to create a sense of extreme tragedy or futility. By eliminating all the characters, the author might be trying to show that in the world of the novel, there is no hope and all are doomed. It could also be a very extreme form of making a statement about the futility of life or the overwhelming power of certain forces, like a cruel and inescapable fate or a devastating event such as a global catastrophe that no one can survive.
To set a dark or tragic tone. If an author wants to show that the world of the novel is a harsh place from the start, killing off a character early can be an effective way. For instance, in '1984', the way the Party eliminates people early on gives a sense of the totalitarian and dangerous world.
One effect is that it can create a huge shock for the readers. It completely changes the expected narrative direction. For example, in 'Game of Thrones', the death of Ned Stark was a turning point that made the story more unpredictable and full of high - stakes drama.
Sometimes, it's a way to show the harsh reality of the story's setting. If it's a war - themed novel, killing many characters can depict the horror and destruction of war. Like in 'All Quiet on the Western Front', the large number of deaths among soldiers effectively conveyed the brutality of World War I.
It can make readers sad. If they've become attached to a character, that character's death can be quite emotional. Like when we read about the death of Dobby in the Harry Potter series.
One possible reason could be a lack of trust. If one of the engaged parties discovers that the other has been lying about something important, it might lead to calling off the engagement. For example, if there are hidden financial problems or a secret relationship in the past.
Well, poverty is often a big factor. When families can't afford to feed all their children, they may make the tragic decision to sell some. Sometimes, it's the result of human trafficking where siblings are sold without the family's real consent but are tricked into it. And in some areas with lack of proper laws and enforcement, unscrupulous individuals can take advantage and buy and sell siblings for various immoral purposes.
Sakura's obsession with Sasuke. Naruto might be fed up with how Sakura always puts Sasuke first, ignoring the people around her who truly care about her, like Naruto himself. So he tells her off to make her realize her wrong priorities.
One reason could be time. If you're in a situation where you don't have much time to tell the whole story, you might cut off the end of the roast story. For example, if you're chatting during a short break.
Sometimes, the activities the girl is doing can lead to it. If she is involved in a sport like running or climbing, the skirt might get caught on something like a branch or a fence. Also, if she is dancing energetically, there is a higher chance of the skirt getting twisted and ripped.
