This article, which talks about the way fantasy and sci-fi fans react to characters being killed off, reach a conclusion I find ridiculous:

I believe the discomfort comes down to the base fear of death and uncertainty that people face every day. Death is a subject that makes people uncomfortable. It doesn’t surprise me then that people would have such emotional reactions to fictional character death. They come to fiction to be taken away from the concerns of their everyday life. When confronted with the sudden death of a beloved character, viewers and readers are jarred into dealing with the uncertainty of life in their fiction and that can be unnerving. Look at reactions to the first murder in Psycho, or the death of Cedric Diggory in Harry Potter as examples outside of Martin and Whedon if you will, as they’re not the only writers who use the tactic to drive the emotional point home.

This is psychoanalytical bullshit. The reaction of fans is much more down to Earth. They realize that these characters are fictional. And so killing them off is the writer’s choice, not something that just happened. Even the phrase “killing them off” acknowledges this.

What fans object to is not a character dying, but a character being killed in what feels like an arbitrary and capricious way. No one — NO ONE — objected to Spock being killed in Star Trek II. It was a great way to go, it was an emotional wallop and it was utterly consistent with the theme of the movie and his character. It was one of the best moments in the movies. People did object to Data being killed in Star Trek: Nemesis because it felt arbitrary and stupid. There was no reason for it to happen other than to shock us and try, unsuccessfully, to recreate the punch from Star Trek II.

Numerous sci-fi/fantasy deaths are well-regarded: Theoden’s fall in Lord of the Rings, Vader in Star Wars, Roy in Blade Runner, Ries in The Terminator, Kong in King Kong, Theo in Children of Men, Kosh in Babylon 5, the Knight’s pending death in Seventh Seal and Dumbledore’s fall in Harry Potter. All of these were cases were the death was consistent, reasonable and even noble.

If you look at the deaths that are poorly regard, they tend to be of the arbitrary “eh, shit happens” type: Trinity and Neo in The Matrix Revolutions, Padme in Revenge of the Sith, Ripley in Alien 3 or almost all the death in The Dark Tower.

I have not seen Game of Thrones or Buffy, but I did see Serenity. I didn’t object to the characters being killed. What I most objected to was Wash being killed so arbitrarily (and even then, I didn’t object that much, even though I loved his character). Yes, life is like that, especially a dangerous life. But we want to see our characters go down fighting, to die for a reason.

I mean, seriously: you’re going to take us on a journey with magic and swords or laser guns and faster than light travel; and suddenly you want to be all realistic when it comes to the characters being killed?

That’s the problem. We realize that we are in a fantasy world. And if our characters are going to go down — by the choice of the writer — we want them to go down for a reason.
