 The first draft of the script introduced the character as John <unk> — who is revealed to be a man involved in " The First World Tyranny " , named Ragnar Thorwald . The character of Thorwald was more brutal than Khan in the final version , killing guards using a phaser . In the original script , Kirk forgives <unk> and offers him and his people a chance at a fresh start — something that remained in the final episode — but the character committing murder would have precluded such an ending , as NBC censors would have necessitated the " bad guy " be punished for his actions .
