If I were a supervillain, I would end capitalism, racism, sexism, homophobia, transphobia. . . but I guess that's a little too obvious and not villain-y enough. Because that's actually being a superhero. I would break down poverty with my machete; I would end world hunger.
There's so much power in allegory, to form ideas and learn lessons that you can actually take and apply to real life. I think that's why I originally really loved fantasy and reading.
