If you want your story to be the best it can be, you have to write and rewrite your story, a lot. There are very few authors out there that can nail their novel on the first draft and those that can have been writing for so long that the final draft comes naturally to them because they have already worked the story in their mind three or four times before putting words to page.
Character death is a necessary evil that some writers try to avoid. Naturally, I’m not speaking to novels that don’t involve death in some fashion such as a romance novel or a coming of age story for a football player. I referring to novels that involve danger of some kind. Dangerous situations make a story exciting and offers a way to show how our character grows through adversity.
Danger is a classical and important device used in stories. It is exciting for the reader and, for me at least, fun as hell to write. There comes a point, however, when constant danger gets stale and the danger just becomes another part of the scenery. This happens when characters never die. No matter how much danger you throw at them, your main character and their friends survive it. It is a disservice to your reader, yourself, and your characters.
