The Bad Boys For Life ending has Will Smith’s Mike Lowrey confront his past, while Martin Lawrence’s Marcus Burnett decides about his future – and together, they put an end to an extensive killing spree that sets up Bad Boys Ride or Die. Coming 17 years after Michael Bay’s Bad Boys 2, Adil El Arbi and Bilall Fallah successfully revitalized the long-dormant franchise with Bad Boys For Life. The movie begins with Marcus’ daughter having a baby boy with her longtime boyfriend. Marcus looks back on his life, particularly his life of violence, and decides to retire.
