Ricky Williams changes his name.

The guy is a nut case
Guy who shoots up a church or school is a nutcase, guy who storms the capitol in a buffalo hat to subvert democracy is a nutcase, guy who keeps his own daughter locked up in the cellar for a decade and has a child with her is a nutcase.

Ricky has a different way of living his life, that fits his view of happiness, and though it does not fit social norms functions within society with near zero impact on anyone elses lives. Not a nutcase.
