Being killed instantly while thinking of your favorite pastime doesn't sound so bad. They should have said that a heavily disfigured Chuck somehow survived the gory mangling and was forever stuck in an outwardly vegetative state while his fully alert mind was left to rot in an emotional vacuum. Being fully conscious but unable to control your own body or communicate with the outside world would seem far worse to me than any sort of instant death.
For a publication aimed at schoolkids, the writing is wildly inconsistent and uniformly bad. Perhaps somebody adapted the booklet from an educational film written and directed by Ed Wood.
