It's always some self lothing coward who hasn't acomplished anything. The star of their own daily pity-party who thinks everyone diss-ed them because they wear their insecurities on their sleeve. When they pick up a weapon..........well now their someone to be reconded with, the power fills their scrawny little mind. When they discover they can no longer tolerate being the loser on display, having everyone witness it, they decide it's time to kill the "witnesses".
