To cover a little bit of new ground... one of the things I don't see mentioned a lot is how casually racist he is. The most obvious examples would be his rather off-color remarks to Gomez. Maybe it's "all in good fun" or whatever, but I have to wonder how Gomez really feels when Hank makes yet another crack about wetbacks or beanspeak. Those comments certainly seem to indicate an inherent distrust of hispanics -- perhaps bred by the job, or perhaps always present in Hank in some form.
Another example is Hank's reaction to the revelation that Walter bought marijuana (supposedly at least) from Jesse, versus his reaction to the mexican janitor he busted at Walt's school. Hank seemed pretty lenient about Walt's dope-smoking, but when quizzed about the janitor (who you'll remember was only found to have pot in his possession), Hank said something like "he'll be fired -- as he should be!" Maybe this double standard is because Hank knows Walt personally, but then again maybe not.
Like the rest of you, it seems to me that one of the major themes on Breaking Bad is that everyone has a dark side. To that extent, Hank has come out looking like one of the most moral characters thus far. But I do think there's at least a little racism in him if nothing else.
