A Bit of a Scoundrel
Although Han Solo associates with underworld kingpins, gamblers and space pirates, this does not bar him from genteel society.
Han Solo exhibits bravery, ingenuity and honesty, first-rate qualities.
Most importantly, Solo does not lose himself in pursuit of his goals (be they a relationship with Princess Leia, freedom from the tyranny of the Emperor or a working Hyperdrive for the Millennium Falcon). He maintains the traits that distinguish him from others while compromising his baser instincts for a softer demeanor.
