The man he is lungeing at is Juror #8 (Henry Fonda), who isn't convinced of the accused's guilt and wishes to go over every shred of evidence carefully. As he gradually convinces other jurors to question their snap decision, Juror #3 becomes more agitated and angry. Finally, goading him, Fonda's character accuses him of being a sadist who wants to see the boy executed no matter what the evidence proves. Cobb's character loses it and tries to attack Fonda, having to be held back by several of the other jurors.
