Yes.
Complete Scoundrel's sample media characters with alignments, might be a useful place to start- for comparison.
Han Solo is listed as TN
Mal Reynolds (Firefly) is listed as CG
Jack Sparrow (Pirates of the Carribean) and Al Swearengen (Deadwood) are listed as CN
Riddick (Pitch Black) Sawyer (Lost) and Carl Denham (King Kong) are listed as CE
Is Conan more Chaotic than Han?
Is he less Good than Mal Reynolds?
Is he more Good than Jack Sparrow?
Is he less Evil than Riddick?
These sort of comparisons might support the CN suggested alignment.
Interesting, but I never saw Riddick as Chaotic Evil. He did go back eventually, even if it was with a little prodding. Or was that his alignment change?
