After breakfast the host takes the young man into a corner, and explains to him that what he saw was the ghost of a lady who had been murdered in that very bed, or who had murdered somebody else there - it does not really matter which: you can be a ghost by murdering somebody else or by being murdered yourself, whichever you prefer. The murdered ghost is, perhaps, the more popular; but, on the other hand, you can frighten people better if you are the murdered one, because then you can show your wounds and do groans. ("Introduction" to TOLD AFTER SUPPER)
Jerome K. Jerome
When I saw photographs of children murdered by the Fascist, I felt furious pity. When the supporters of Franco talked of Red atrocities, I merely felt indignant that people should tell such lies. In the first case I saw corpses, in the second only words. . . I gradually acquired a certain horror of the way in which my own mind worked. It was clear to me that unless I cared about every murdered child impartially, I did not really care about children being murdered at all.
Men and women in my lifetime have died fighting for the right to vote: people like James Chaney, Andrew Goodman and Michael Schwerner, who were murdered while registering black voters in Mississippi in 1964, and Viola Liuzzo, who was murdered by the Ku Klux Klan in 1965 during the Selma march for voting rights.
Put yourself in Hamlet's shoes. Suppose you were a prince, and you came back from college to discover that your uncle had murdered your father and married your mother, and you fell in love with a beautiful girl and mistakenly murdered her father, and then she went crazy and drowned herself. What would you do? Go back for a masters?
If I had a brother who had been murdered, what would you think of me if I...daily consorted with the assassin who drove the dagger into my brother's heart; surely I too must be an accomplice in the crime. Sin murdered Christ; will you be a friend to it? Sin pierced the heart of the Incarnate God; can you love it?
I would look at the first chapter of any new novel as a final test of its merits. If there was a murdered man under the sofa in the first chapter, I read the story. If there was no murdered man under the sofa in the first chapter, I dismissed the story as tea-table twaddle, which it often really was.
Death, there will be death, aye. Your lordship lost a son at the Red Wedding. I lost four upon the Blackwater. And why? Because the Lannisters stole the throne. Go to King's Landing and look on Tommen with your own eyes, if you doubt me. A blind man could see it. What does Stannis offer you? Vengeance. Vengeance for my sons and yours, for your husbands and your fathers and your brothers. Vengeance for your murdered lord, your murdered king, your butchered princes. Vengeance!
George R.R. Martin
Do you think she is?" Her voice trembled. Her heart throbbed as she waited for him to answer. "You think they've killed her?" Every moment wrapped around Scarlet's neck, strangling her, until the only possiblbe word from Wolf's mouth had to be yes. Yes, she was dead. Yes, she was gone. They'd murdered her. These monsters had murdered her. Scarlet pressed her palms into the crate, trying to push through the plastic. "Say it." "No, " he murmured, shoulder sinking, "No, I don't think they've killed her. Not yet." Scarlet shivered with relief. She covered her face with both hands, dizzy with the hurricane of emotions. "Thank the stars, " she whispered. "Thank you.
I also remember when I watched Henry: Portrait of a Serial Killer  at, like, age 15. That scared the crap out of me. Because it didn't operate inside the usual conventions of the horror genre in the way that I could accept. I can accept horny teenager counselors being murdered at camp. But I couldn't accept the derangement of Henry: Portrait of a Serial Killer, which was that anyone could be murdered at any moment - whole families, with no build-up music and no meaning. It terrified me.
Although I was an imaginative child, prone to nightmares, I had persuaded my parents to take me to Madame Tussauds waxworks in London, when I was six, because I had wanted to visit the Chamber of Horrors, expecting the movie-monster Chambers of Horrors I'd read about in my comics. I had wanted to thrill to waxworks of Dracula and Frankenstein's Monster and the Wolf-man. Instead I was walked through a seemingly endless sequence of dioramas of unremarkable, glum-looking men and women who had murdered people - usually lodgers and members of their own families - and who were then murdered in turn: by handing, by the electric chair, in gas chambers. Most of them were depicted with their victims in awkward social situations - seated about a dinner table, perhaps, as their poisoned family members expired. The plaques that explained who they were also told me that the majority of them had murdered their families and sold the bodies to anatomy. It was then that the word anatomy garnered its own edge of horror for me. I did not know what anatomy was. I knew only that anatomy made people kill their children.
