Writing Challenge - Week 23

This month we are focusing on a more sci-fi take. I don't write sci-fi myself but I have often been asked certain philosophical questions that are really interesting to think about. One of the most popular questions is if you could go back and change certain things in history would you? This question is often about bad men who did something to alter the course of history.

So today's challenge is to pick a historical event that you would go back and change if you could. Make sure to add how you could change things, what the outcome would be of your changes, and how it would affect life as we know it. A great example of this, should you need one is Stephen King's 11/22/63. In his book, he looks at the Kennedy assassination and how life changes depending on the things the main character does. It is very important to think of the political repercussions this would have had, etc.
