The fact Dak'Rah was a coward and let his men die so he can escape that moon assures his place in Grethor.I always felt something got lost in context. Klingons practice total war and it is better to die than be taken a captive but not every klingon believes these principles (and much of it is hyperbole--see Terry Pratchett and Cohen the Barbarian). So as Quark demonstrates, while it's not against their law to slaughter civilians, there's no glory in it either.
