I personally like Captain Beatty. He is an enigmatic bad guy; he's aggressive and threatening, but layered. He reveals that he has read books, that he has been moved to the point of being "ready to blow up the world...destroy authority", and then he turned his back on those same books because, according to him, "What traitors books can be! You think they're backing you up, and they turn on you." But yet he still has a lot of quotes from them memorized, and can whip them out at any given moment, to use in arguments. He is obviously very intelligent. His turning on books makes me feel like he has experienced life-altering betrayals that have created the multi-dimensional character that he is. Right before he dies, he rants against peaple like Clarisse, saying, "They rise like the midnight sun to sweat you in your bed," which seems to indicate that he has had a bad experience with someone just like her; maybe that person betrayed him. And then, of course, after Montag kills him, he realizes, "Beatty had wanted to die." So despite all of his talk about how firemen are around "to keep people happy," despite his ranting against books and do-gooders, despite his adamant support of their society's ways, Beatty was deathly miserable. I find all of that very intriguing, and that is why I like Beatty so much.
