As you probably already know, the title of a paper is important. If your theme is on the topic of "fair is foul and foul is fair," then you can be creative in many different ways. In light of this, let me suggest a few points that might help you find a suitable title.
First, since the theme of your paper is on reversals, anything that deals with this topic would be appropriate. Here are some words that might help you think about a suitable title: "paradox," inversion," least expected," and the list can go on.
Second, if you particularly like a sentence in your paper, you can distill that sentence and make it into your title. Of if there is a word in your paper that capture the essence of your thesis, you might want to make that into your title.
Finally, you may want to take a word or words from another famous work as your title to make an allusion.
