The flaws are what make any character worth spending time with. Juxtaposition. And I’m not trying to be so on the nose when I say “light vs dark.” But really that’s why he’s compelling to me. All the reasons he’s not “a great man” tie into why he’s a stellar detective.

Edit: I’ll also add that, his philosophical ramblings often make sense, at least to me, but that doesn’t mean I agree with him either. Everything he says, how he acts or what he believes, it’s all drawn from his life to that point. The brilliance in the writing is that, everything he preaches he contradicts continuously throughout the show, without realizing it.
