First is Raylan Givens from Justified:
Now, for a different kind of Lawful Good character:
...Andrew "Ack Ack" Haldane from The Pacific! The quote is the perfect definition of his character: he fights both for the safety of his men and for his idea of goodness. Obviously, this sort of Lawful Good character is more easier to discern: in the context of the Pacific, people like him, in comparison to the rest of the soldiers, appear as the big "good" in the series. This doesn't make him any less compelling of a character, however.
That's all, next time, I'll post some neutral good characters!
