I recall finding the Kira/Dukat story interesting- I mean, the Cardassians claim to have these high family values, but when they commit adultery, they have no qualms killing the children, and lets face it, most of those Bajoran women, no matter what the Cardassians say, were sex slaves. "Indiscretion" indeed. -_-
The way I've seen it...there is VERY clear evidence the military has a culture that promotes such atrocities. We've seen that time and time again, and Dukat is the quintessential example of that.
On the other hand...as much as I HATE to give any sort of credit to Dukat--he did ultimately put it all on the line for Ziyal.
But if you want to see an example of Cardassian family values WITHOUT the Dukat taint--check out Tekeny Ghemor. The astonishing thing about
that was that his feelings continued even after he knew beyond doubt that Kira was not his child by blood, nor even the same race.
I suspect that just as in our society, people talk the talk--but only those with character walk the walk.
