sociopathic-compulsions:

On May 21, 1998 15-year-old Kip Kinkel first murdered his parents before opening fire at Thurston High School, killing 4 and injuring 25. However, long before the shooting, Kinkel had been obsessed with guns and the idea of violence. The future killer frequently bragged about building explosives, and even lectured his literature class on how to make a pipe bomb. Kinkel also boasted about how he would torture animals, claiming that he would stick firecrackers in cats’ mouths and skin squirrels alive. Once, Kinkel also said that he had blown up a cow. The boy’s parents took him to anger management classes, hoping their son’s behavior would improve. At one point, Kip asked for a gun, and his father bought him a .22 caliber rifle, hoping that if he took him to a shooting range and let him use it there, it would help control his obsessions. Kip’s father later boasted to a tennis partner that he was “pleased with Kip’s progress.” When Kip became suspended and faced expulsion for having a stolen .32 caliber pistol in his school locker, his father still stayed hopeful, and was “surprisingly upbeat” about trying to work out the situation with his son. Little did he know that just hours later, he would be dead at the hands of Kip.
