Meth is the most fucked up drug when it comes to the long-term effects on the mind as it floods your dopamine receptors with 1300% the nominal amount of dopamine in a controlled environment, so it'll make you associate anything with intense pleasure if you combine it, no matter how evil. I've always hated meth after seeing it change, take, and even kill my peers and friends. But this is just so intensely evil, and ritualistically evil. This slaps of outside influence that relied on enough data gathering to know where the authority figures would be and that this center wouldn't have excellent defenses, it feels like one of the Manson murders, only even worse in the case of sheer nightmarish sadistic evil. My strongest wish is this man is buried in an unmarked grave and forgotten forever and that each one of these children have graves that are tended and remembered for generations to come.
