>This destabilizes certain minds to become suspectable to outside control.
Not only are the susceptible to being controlled, they are also made to act crazy so they are also suspected. A lot of these kids were known to "act crazy" for quite a while. What if they were being driven to act that way.
This way it's no surprise when they do it. It makes it harder to believe that some nefarious intelligence organization is causing people to go on mass shootings. From a moral perspective it's one of the evilest things I can think of.
