David

As a child, David often served as caretaker of his younger brothers and sister while his parents were at work. When he was 17, David eschewed his responsibilities for one night and went to a party with his friends. While he was gone, one of his two younger brothers broke into their father's gun cabinet and accidentally killed David's other brother. Mere weeks later, David fell asleep before giving his epileptic sister her medication and she died of a seizure in her sleep. Unable to deal with the guilt from their deaths, David became an excessive eater, eventually reaching 413 pounds.
