Kid was basically crying out, saying he had violent thoughts. Dumb parents thought the better idea was to get him a gun and let him shoot at targets “to vent his anger.”
Meanwhile they continue neglecting him, leaving him home alone all the time so the deadbeats can go to the bar and drink all day and night.
Meanwhile the kid is bullied relentlessly at school. I don’t condone what he did but it’s a miserable existence. Unfortunately whether it’s based on personal experiences or genetics the harsh reality is some people turn to either suicide or homicide when there is no other hope left and their world stability had completely shattered for years and no end in sight.
