From Ray Bradbury's Fahrenheit 451, what are some of Captain Beatty's conflicting traits?

Captain Beatty assumes the role of the antagonist for Bradbury's Fahrenheit 451. Some of the best-written villains are those who are not solely evil, but who also encompass human qualities also expressed in the protagonist. This is the case between Beatty and Montag. They are both firemen, whose job it is to go out and destroy people's homes along with their books; and, they both gain interest in books because they wonder what they are missing in life. The conflict between the two is Beatty does not find any satisfaction from reading books, so he assimilates with society, forgets books altogether, and never looks back. Montag, on the other hand, finds the value of books and risks his life to escape the book-burning society. 

Bradbury does a wonderful job unveiling Beatty's conflicting traits. First, Beatty shows concern for Montag by showing up to his house when he calls in sick. Then, Beatty breaks down the history of book burning and seems to give Montag a redeeming chance for going a little wayward from the values of the society. In this case, it seems as if Beatty is good and cares about Montag. Unfortunately, Beatty is a product of the society and ultimately has Montag burn his own house down when neighbors report him for having books. 

Another conflicting quality is that Beatty shows Montag in a later verbal smack-down that he is in fact well-read! Beatty isn't just some ignorant follower of the government, he had doubted at some point in his life, too. He read probably more than Montag because he is knowledgeable and clever with his arguments. Thus, he uses passages and quotes from literature to refute any claims Montag might have to preserve books. In the process of showing off his mental library, Beatty brags:

"Oh, you were scared silly, . . . for I was doing a terrible thing in using the very books you clung to, to rebut you on every hand, on every point! What traitors books can be!" (107).

In summary, Beatty's conflicting traits are that he seems to care about Montag, but does not flinch when it is time to burn Montag's house. Beatty is well-read and understands books, but has chosen to fight against their preservation because he didn't find any redeeming quality; if anything, Beatty seems to have gotten more confused by reading books, which is the complete opposite of what should happen.
