You stare ahead blankly in utter and complete disbelief, your friend is dead. Murdered right before your very eyes. How will you ever recover from this? I mean sure they’re fictional, but they were your best friend.
There are many considerations that must go into killing a character, and deciding whether or not a character will receive the death penalty is never easy. I am by no means an expert, I am however a reader and as a reader I have been gifted a bit of insight into the world of character murder. I know when it works…and when it doesn’t. There are many reasons you might care about this topic at all, the two main ones are: secretly you’ve always dreamed of writing a novel, and now you will have been initiated into the depths of murdering characters, or two you just read a great book and your favorite character just died, now you will understand the level of thought and emotion that went into the authors decision, unless it was George R.R. Martin, he just killed the sucker cause he could.
To keep things simple you should consider two main things: motivation and emotional impact.
