There's only 2 ways to live - either crime doesn't pay or crime does pay. The way to answer that question is to see who's in control of the world. Crime makes sense if this world is controlled by criminals, by luck or by predetermined fate. You could mis-read this part of Esther to think those things are in control. But as the humble and righteous Mordecai (and then Jesus) is raised to the place of power, it shows us that the world is controlled by the righteous God's providence. So crime doesn't pay and living God's right ways is the only way to live that makes sense.
