Antagonist vs. protagonist

For the task like this is play Hamlet absolutely perfect, because whole play is about fighting between couples of characters. Main fight is between danish print Hamlet and his uncle which killed his father. These two people are absolutely different Hamlet in kind of normal guy which want only to find fathers assassin but on the other hand his uncle is terrible kind of person! they are like to magnetic poles one is + and second is -.

Other character do not have such a big fights between each other and there is only one character which fights only with himself and that is Othelia, she fights her own fight in her mind ( she is kind of crazy...=)
