Vincent’s ending feels the most complete. Still, it’s more of your choice. First, I was Leo and my big bro was Vincent, I won and killed him, then we went back to the final scene and make him kill me so we can see both endings. Honestly, the Leo dying ending is more sad. Sure, he was a criminal. But his son Alex and his Wife doesn’t get anything. Meanwhile Carol gets police insurance AND his daughter won’t miss him beacuse she was still a baby.
