Anyone read Alan Moore's classic graphic novel, "The Watchmen"?
Rorschach, a constumed vigilante, tracked a man who had kidnapped a young girl and fed her to his German shepherds. He cornered the man in his shed and handcuffed him to the workbench. He handed the man a hacksaw and picked up a gas can. "Shouldn't bother sawing through handcuffs," Rorschach said to the man. "Never make it in time." He then set the shed on fire.
As Rorschach later told the prison psychologist, "Stood in firelight, sweltering bloodstain on chest like map of violent new continent. Felt cleansed. Felt dark planet turn under my feet and knew what cats know that makes them scream like babies in night. Looked at sky through smoke heavy with human fat and God was not there. The cold, suffocating dark goes on forever, and we are alone... Live our lives, lacking anything better to do. Devise reason later. Born from oblivion; bear children, hellbound as ourselves; go into oblivion. There is nothing else. Existence is random. Has no pattern save what we imagine after staring at it for too long. No meaning save what we choose to impose. This rudderless world is not shaped by vague metaphysical forces. It is not God who kills the children. Not fate that butchers them or destiny that feeds them to the dogs. It's us. Only us. ... Was reborn then, free to scrawl own design on this morally blank world."
