He tells them to go away, calling them ‘You little satans!’ and then the children′s faces become ghoulish and they begin snapping at him, trying to bite him. A short time later, we see Judas being chased by about a dozen of these children; he falls and they kick and hit him. Twice, we see the figure of Satan (recognizable from the opening scene) standing among the demon-children.
