Antagonists use to have not so good tendencies and agendas. The "rule" says that antagonist should be a bit stronger than protagonist. It's hard to make interesting stories with overwhelming protagonists. But... If antagonist is strong and not so good... How bad he/she/it should be? One way to think about this is to divide "bad" to different categories. Like these three. 1. Antagonist as an opponent. The dominant feature of antagonist is that he/she/it tries to get the same thing that protagonist is seeking. Or he/she/it is trying to prevent the suceeding of protagonist because of conflict of interests. Sport stories, competitions... Opposition is between agendas and goals. "We both want that ice cream and I'm gonna be there before you." 2. Bad opponent. Antagonist has different value structures than protagonist. Good guy vs. bad guy. Police vs. criminals... Opposition is between different kinds of values and different means to pursue them. "I know it is your ice cream, but I want it and I'm gonna take it." 3. Evil opponent. Antagonist is outside value structures. He/she/it is evil for the sake of evilness. Opposition is between is anything valuable or not. "I'm gonna destroy all but one ice creams and I'm gonna poison that only one and give it to that nice and kind toddler." Type of antagonist ≈ type of story? I think that the category of opponent is often the base under the story. The type of story rises from that base. And the type of audience you are seeking rises from that too. And you can find these typologies from real life, history and this day too. Comments? Examples? Other typologies?
