Sam Witwer, the voice of Darth Maul in Solo: A Star Wars Story, explained that he thought Solo was about Qi’ra’s effort to keep Han on the straight and narrow. Here’s what Witwer said to CinemaBlend….
“It doesn’t occur to you the first time, but the second time you see the movie, that movie is really about Qi’ra trying to save Han Solo’s soul, because she knows he’s gonna follow her all the way to hell if he has the chance, so she has to break his heart. She has to keep him away from the darkest elements of the universe. She has to keep him firmly out of hell and ascending, which his trajectory as a character is to ascend, and she knows that. But that ascendant quality that Han Solo has, that good guy quality could be corrupted and used in the opposite direction, because she knows where she’s going and she knows he doesn’t belong there. So if you want to really illustrate that, and you need to keep that criminal, dark side element in the background and keep it mysterious, then yes, it’s a smart move to use something that George Lucas had already established elsewhere and suddenly introduce that in there.”
