Well it seemed like an accident at first but definitely intentional as we know now. And after reading Mr. Stack's manifesto, he's definitely not crazy but sure as hell pissed off. And not just your usual "I hate IRs" but seems to have the Che Guevara argument. After reading it he seems to be an anarchist but asking for a socialist society which makes sense if you know anything about socialism that Karl Marx wrote about.
I mean I don't want to come off as silly here, but a lot of what he writes is well true. I actually think he hit a lot of things dead on. Sad thing is though he reacted to it very poorly and this is what happens. But I think yall should try to read his manifesto he liked. It's quite interesting.

In no way am I defending his actions but I do like a lot of the things he said.
