Sounds like he was planning more than spraying bug spray and hacking with a machete, but maybe didn't have the smarts to get it together and do serious damage ...
Freon? Oh hell if it was R-12, he is in for it now. EPA will get involved, and the greenies will get after him for trying to destroy the ‘ozone layer’...
Probably resurrect him so they can torture him to death.
Pretty dang useless as a bomb building material though.
