Well he played the part as a bit of a coward rather than the blood thirsty warrior types like Kor and Kang! Showing us that not all Klingons had honour even then!

Honor is such a subjective thing, though. Kor was angry to be governor of a planet of sheep, but he had a fleet and an army backing him up. Kras was trying to get a foothold on Capella by himself, I don't think that's a cowardly act. Even Kang didn't seem especially honorable to me, just not stupid. Only a fool fights in a burning house.
