Death mask (1995)

Wilbur works in an old carnival and shows some gruesome things to the public. He covers his face because he had a sadistic father who burned his face as a child. Everybody makes jokes about his scars and when the new boss fires him, he goes to an old swamp-witch who gives him a peace of wood from a hanging tree. Wilbur makes a mask from this piece of wood and puts all his anger in this mask. When he puts the mask on, everybody who looks at him commits suicide.
