Killing characters is something that is often a part of every story. A good way to make conflict and create a necessary plot point, but it also has to do with being properly executed. On one hand, if one does not kill a character, in certain stories, like those of adventure, it make stakes look shallow and soft. On the other, if someone kills too many characters, it becomes essentially impossible for anyone to grow attached, or even like a character, which often creates a tension which is difficult for writers to overcome. Finding that sweetspot.
The question thus remains, how does one kill off characters properly. It it quite simple to answer, but depends on a story. it is very likely that things such as comfort stories will not require any sort of death for the story to be good, however it is also likely that a high fantasy book, or one of great political intrigue, will need death to fuel stakes of the story. That of course, gives us our answer to what the correct way to go about killing characters is.
In the end, the right way to kill off a character is to kill them when the story demands it. If a character dies, it should fit the narrative of the story. It shouldn't seem forced, and it should either fit the natural course of events for the character's lore and set up, or it should be a reasonable expectation in the framework disposed for the book. Either works, or both, but that hels things not look forced and makes the events flow naturally.
