Now, all authors excel at some things and...excel less at others. Some are quite good at making magic with words (like Patrick Rothfuss). Others weave the plot so perfectly that you're reeling for days after you finish a book (like Brandon Sanderson). Others have many cool devices that keep you interested (like sci-fi). Most of these things accrue mental points during the reading. The prose that makes you think. The plot that blows your mind. The devices that intrigue. The political structures. The worldbuilding.
But there's another category in which to score points. This happens when you build compelling characters and convince us of how they react in a situation. Make us fall in love with that girl your protagonist is falling in love with. Make us laugh when a side character does something characteristically silly. Make us cry when loss occurs. Make us furious when the enemy prevails. Make us glory when the protagonist succeeds. Make us feel.
Here's the thing. Every book that you start reading is an investment. An investment of time and emotion. I'm committing to spending maybe ten hours with these characters; they had better well make my investment worth it!
Which brings me to the main point I want to make: POV character deaths. Let me describe exactly what an author does when s/he kills off a POV character. If you've done it right, I've developed an emotional bond with this person. If you've done it right, I'll be devastated when it happens. I might accept that it needed to happen, but that won't make me any less distraught.
Killing off a POV character, specifically the protagonist, is like having a spouse die or divorce you. It's someone you've grown to love, now they're gone forever. For POV characters with less ink to their names, it's like dating someone you love and getting broken up with. It's an important and powerful literary device and can be used very well and to great acclaim.
But imagine this: you start dating someone, even fall in love with them, but you're almost 100% positive they're going to break up with you. That might be okay once. You can take that emotional battering. But imagine there's a slew people waiting to date then break up with you. You're not going to want to go through that turmoil.
It's the same with killing off characters. If you kill off nearly every character you write, I'm getting crappy returns on my emotional investments. It's a tool, but like any tool, it can be over used. It can be the emotional analog to building up to a great climax, and then finishing with a lame cop out. I'm not going to want to read 200 pages about a ton of characters if I know they're just going to die at the end.
Just because something is realistic doesn't mean it's worth writing about. People browsing the internet for hours a day is real, but it would make a crappy book.
This post may or may not have been an A Song of Ice and Fire rant in disguise.
