I'm not really familiar with school shootings at all, but do all the perpetrators really do it for the fame or infamy? What message are they trying to get across?

I think they're just doing it because they enjoy disrupting civil equilbrium by causing chaos.
I'm not sure that this case had anything to do with fame. The first person shot is the mother of the shooter and then he turned on her class. The principal and other teachers got shot when they got in his way leaving the building. He tried to escape by car, but committed suicide when he was surrounded by SWATs.
