HIGH SCHOOL shootings.
If you have been habitually bullied before you would understand. Your mind goes to dark places.
99% of people have that block in their heads that say, killing is wrong, revenge solves nothing. Its the 1% that don't. Fantasists, Psychopaths and Sociopaths, are classed as weird and cast out from the school society and even targeted for bullying. Cause to effect, their conditions mean that they have no inhibitors to violence and essentially no conscience.
Hence if they are not treated by a psychiatric specialist or on medication. The result can be tragic.
The example of this is Columbine, Eric Harris suffered various psychiatric conditions, and was bullied as a result, his friend, Dylan, was also bullied because of their association and hence, they pledged revenge, which they conducted.
I do not mean understandable as a justification, I mean it in the sense that you can understand WHY.
It is not right.. in any way shape or form, but the cause is clear.
My point is why would ANYONE, shoot up a Primary school...... why?
