Do you like to kill off your characters? George R. R Martin does because he want his readers to care and fear about his characters' safely. I find his strategy to hook his readers very interesting. When I watch action movies like James Bond and Rambo, I know the heroes will always escape from death. It isn't interesting unless you think your favorite character will suddenly die. I'm think all killing off my main characters in their final book just to freak out my readers as a conclusion to the characters' epic quest. But that is just a thought. Some authors said it is hard for them to kill off their characters. I guess because they care too much about their characters. However, it can be interesting if the hero dies after or before they save the world. What do you think?
