I've been a victim of bullying. This is why I understand school shooters. People don't understand how damaging bullying can be?

Many people have committed suicide because of bullying. I was bullied for a time, it was horrible, so I cannot judge school shooters and say "oh you had no reason to do this". These people have been bullied so much, that the alternative to school shooting was going to be suicide anyways. I believe this problem needs to be addressed seriously, these people were not born monsters, they were pushed to become monsters because the law failed to protect them from bullying
