Francis did what was best for him, it's his life and he has made money which is enough for a lifetime. However, it was very clear that he didn't belong in the ring at this level. My first impression of the Fury fight was also, wow, but I watched it again and neither one didn't look very good in that fight, by high level boxing standards.
I also think Francis turned into kind of a diva, but sometimes shows he is still humble, paying coaches alot etc.. But I can never root for grown men who wears sunglasses indoors.
The story might not be over, first time he got stopped sure a bad KO, but his MMA-legacy is filled with what ifs, he got badly outclassed this time.. He has money (but looks like he is a real spender), and did what he thought was best for him. Both a frustrating and inspiring story. I do think he should focus on a few MMA-fights now, and see what happens.
