Hank was more sympathetic than Walt, but he was definitely largely driven by his ego and desire for vengeance, rather than concern for the law in his closing few episodes. I enjoyed this type of storytelling, with ambiguous and conflicted characters. Even Todd got to show a nice side at times.
I often wonder what show some fans have been watching. Especially when I read stuff about Walt declaring he was evil in the finale. Eh? This wasn't Star Wars.
My favourite Breaking Bad character was Mike, and you couldn't pigeon-hole him as a good or evil character.
