Someone who is most of the time mentally ill. This could be cause by abused or a victim of bullying in early childhood. The person may also suffer depression and other mental disorder. What drives them to actually shoot at the school is still a shock to many. Some say, maybe they wanna be remembered, some say, they do it because their fed up with the world, but whatever it is, it's still a mistery to actually know what is going on inside the mind of a school shooter. I personally feel that depressed kids or adolescent need to be taken serious and treated early before they get out of control. And also, people of today are not very nice to each other, so i think that bullying also contributes to school shooter, as they feel very depressed. Overall I think it's a very horrible thing to do, I mean if you're not feelling well, get help or if you really want to die, just kill yourself and not others who have done nothing to you.
Fred: Do you know that kid who always sits by himself and never talk to no one in the class and ge's always sad.
Michael: Yeah i know right, last time i tried to talk to him and he just ignored me.
Fred: I think we better watch out for him, because i suspect that he might be a possible school shooter.
Michael: Yeah, I think so too.
