To be fair, though, Dukat's wife and children were never very important to the character, other than Ziyal. We know he cheated relentlessly on his wife with various Bajoran women he claimed to be in love with. He states that he has seven children as part of the "humanizing" of the character in the early seasons, but the show never deals with them onscreen, and Dukat doesn't seem to show much interest in them (for example, when he is living as a renegade fighting the Klingons, Ziyal is there, but where is the rest of his family?). So, this neglect didn't begin with the Pagh Wraith storyline.
I never said that I believe there was any 'true wuv' between Dukat and his wife, but I wouldn't say that he doesn't show interest in his children, certainly not before season 6 when the writers seemed to forget about them. In Defiant he talked to Sisko about his son Mekor and taking him to some sort of Cardie version of Disneyland. While he was on Ghourmal fighting the Klingons, Ziyal was the only family he had, because his wife had left him and taken the children with her. He whined about it to Kira throughout Return to Grace. Presumably, since his status had diminished so much in Cardassian society due to the 'shame' of bringing home a half-Bajoran child (even his mother had renounced him), there was little he could do about it. This may have changed when he managed to become the leader of Cardassia, but the show didn't address the issue, apart from having Dukat talk about his youngest son in his speech in By Inferno's Light, which seemed to suggest that he is at least still in contact with them. The fact that we never saw them onscreen doesn't say anything about his relationship with them. We know that Garak had something to do with the death of Dukat's father and it kinda seems a big deal to Dukat, but we still never find out anything more about it. We rarely see family members even of the characters in the main credits (apart from Sisko, of course) until they show up in an episode, and Dukat was a recurring character, after all. Damar was in the show since season 4, but we didn't even know he was married until late in season 7, and I think the first time we ever learned we had children was when they were murdered. And we still know more about Dukat's and Damar's families than we know about Jadzia's.
As for Dukat's desire to win approval/respect/adoration... The idea that Dukat was exclusively obsessed with winning the approval of Sisko, Kira, or the Bajorans, seems to come from the late season 6/season 7, when the writers of the show conveniently forgot that she had always also been just as (if not more) concerned with winning and retaining power and status on Cardassia; one of the most memorable Dukat moments in The Maquis is when he learns that the CC wasn't trying to save him, and when he looks deeply hurt because they didn't tell him they were smuggling weapons to the colonists in the DMZ (and it's obvious that he is hurt not because they were smuggling weapons, but because they never told him); in Return to Grace, he is angry because of some gul who is courting his ex-wife and laments that that guy would've never dared to try it while Dukat was still influential (and it doesn't seem that this has much to do with any real feelings on Dukat's part for the ex-wife, as much as with his feelings of pride and possession and the loss of status). Dukat was always a kind of man who wanted to be powerful, respected and adored by pretty much everybody; he did have a special thing for Bajor and maybe even more so, Terok Nor, as both the places he spent a big and important part of his career on, and as symbols of his failure, which he sought to reclaim and prove himself again. But the idea of Bajor and Sisko being the objects of a single-minded obsession to the exclusion of everything else, is a late retcon, and to me, not really convincing. Although it seems that it worked for some other posters.
Overall, the problem with Dukat's characterization is that apparently nobody sat and worked it out at the start, or at least halfway through - basically, they started off just wanting to have a bad guy and never meant to make him particularly complex; then they figured "oh, this guy can act" and started writing some more interesting stuff for him, and for a while they were probably happy for having created a multi-dimensional and popular villainous character, since they liked to think of their show as a more morally complex, "shades of gray" kind of Trek; but as they kept reading the Internet feedback, they (or at least some of them - like the showrunner) thought "oh crap, many people actually like this character - some are even defending his actions!" and got frustrated and alarmed that the show's "moral compass" was lost, so they tried to rectify this by hammering home the point that Dukat was evil... and they went overboard with it.
edit: added because I've only now read
flemm's last post
It seems that it wasn't the suits, but Behr himself who felt he needed assurances about 'not losing the moral compass'. See this interview:
http://trekweb.com/stories.php?aid=SdNrK8202hgIc&mailtofriend=1
Follow-up: I didn't get a chance to follow the link earlier, but just got back to it. I've read these comments before. It's complicated, because many of the concerns raised by Behr in that interview are legitimate.
I don't like how Dukat's involvement with the Pagh Wraith was handled, especially at the very end, but becoming apologists for the racist ideology Dukat espoused, as the show risked doing in the middle seasons, notably in
Indiscretion, would have been ten gazillion times worse.
Whoever wrote
Indiscretion (I don't actually recognize their names, but anyway the producers signed off on it), seem to think there might actually be some disagreement about whether or not the Occupation was beneficial for Bajor, and therefore justified. Riiiiight. Next we will be hearing about how the Holocaust was justified because it led to the birth of modern Israel. And the brutal colonisation of Africa was actually what inspired those nations to seek independance, and so was actually beneficial to them
Watch that scene in Schindler's List where Ralph Fiennes' character is fascinated with the beauty of his Jewish captive, who he has been taught to believe is an inferior being, then let's talk about how much Dukat must have truly loooooved Ziyal's mother and his other Bajoran mistresses during the Occupation. These comparisons are inevitable because the show itself drew these paralells in
Duet and elsewhere.
No wonder Nana Visitor could hardly stand being around Alaimo in make-up, even during the middle seasons when the writers were convincing themselves that Dukat was such a decent chap at heart despite his unrepentant racism, and flatly refused to allow Kira to have an affair with Dukat, as the writers had at one time envisioned. We can thank her for saving the writers from themselves.
These discussions make me sad that Peter Allen Fields had to leave the show when he did, as he seemed to have the best grasp of these matters. This is also what makes
Waltz an important DS9 episode, as it recgnizes the need to return to the spirit of
Duet and delve deeply into the psychology surrounding the occupation, as well as Dukat's patronizing attitude toward the Bajorans, his hatred and fascination.
None of this really explains, however, the comic book villainy of the final arc. Recognizing the ugly underside of Dukat's personality didn't need to lead to mustache-twirling. It could have been handled intelligently, as it is for the most part in
Waltz (save for the very end), and the character could have moved on from there.
EDIT:
Indiscretion is the season 4 episode I was referring to, in which Ziyal first appears, not
Return to Grace, as I had originally written by mistake.
I agree that some of the concerns he raised in the interview are legitimate, and I completely understand his frustration with the reactions of a portion of fanbase - because I'm also read and been majorly annoyed by musings of those fans who, while they like the explosions and/or romance and "cool" characters on the show, can't stand the "boring" "whining" about such things as mass murders, slavery, oppression and genocide, who think that Occupation wasn't that bad, and that Kira was judgmental bitch because she didn't throw herself in Dukat's arms. But, while I understand where Behr is coming from, I am not able to excuse him for trying to answer those problems by adopting a ridiculously cartoonish approach to the issue of good and evil.
For all the legitimate concerns he had, that interview is also full of misguided views, and attitudes that I would've never expected from a showrunnner of a show like DS9. These are the parts of the interview that really make me roll my eyes every time I read them:
"The problem I find with a lot of writers, including myself, is that once you get involved with a character you start to get to know him and you humanize him. Michael Piller did the rewrite of 'Defiant' where he had Dukat talk about his children; My reaction was, 'Uh oh, we've crossed the line.' I realized that he was going to lose all credibility as a villain; we were going to shower him with our usual writerish empathy, and, like all good liberals, we'd see him as neither fish or fowl." "I really responded against that. Here was the guy who had been in charge of Bajor, and right away we were looking for excuses for him.
But actor Marc Alaimo, who had become quite popular with the show's fans, had a different view of the character, seeing him as ultimately redeemable. Behr explains how this actually helped feed into creating the character the way he wanted: "What made it perfect, what made it beautiful, and that no writer could have conceived of, was that Alaimo took it in his head that he was the hero of the series - that Dukat was really just misunderstood; that he was sweet and kind.
"Whenever I think of the character, I think of Renoir's line from 'The Rules of the Game': 'The tragedy of life is that every man has his reasons.' Dukat could logically explain away everything he did, he could find justifications for all of it, and that's the horror; that's the thing Alaimo and I were always in disagreement about. His attitude was, 'We all have this inside of us, we're all many different people, and no one is truly evil.' Then I'd say, 'OK, if you take that to its conclusion, then no one has to stand accountable for their actions.'"
In the end, Behr says he's mostly pleased with how the character met his end fittingly: "I think he got what he deserved, let me put it like that. I can't say I feel sorry for him, I really don't. He and Wynn were two characters I just could not sympathize with. Though we tried in all fairness to give them their points of view and give them their attitudes, they were very deluded, and they did horrible things."
They
tried in all fairness to give them their points of view and attitudes? As if that is such an amazing concession.

That's what a good writer is
supposed to do. Unless your intention is to write a cartoonish show with evil overlords who do things just for the sake of being evil - in that case it's OK to have muhahaha villains without their POVs and attitudes. But then decide right from the start that this is what your show is, and write accordingly. But if you're writing a show that is trying to be realistic, mature, challenging, relevant to the real world, you're supposed to write realistic characters, and realistic characters have
motivations and their own
point of view, because that's what people have in real life. Hitler and Pol Pot and Idi Amin didn't decide to be evil, they believed they were doing the right things.
And yes, every real life criminal and despot was human, they weren't devil-possessed and they weren't an aberration from an otherwise wonderful human race. And most of them had some good qualities, and loved their children or their dogs or whatever. How does that effect their guilt for their crimes? If you think that conceding they were human, or
understanding what they were about is the same as
excusing or
justifying them, you have a very warped view of morality.
But this is the part that really baffles me the most:
His attitude was, 'We all have this inside of us, we're all many different people, and no one is truly evil.' Then I'd say, 'OK, if you take that to its conclusion, then no one has to stand accountable for their actions.'"
I actually happen also to believe that we all have a capacity for good and a capacity for evil inside. And - I don't know how to put this more diplomatically - the conclusion Behr derives makes no sense at all. How the hell does that mean that people are not accountable for their actions?!

I would say it's exactly the opposite: whether you are going to do good or evil, while influenced by many factors, is ultimately a matter of
personal choice - not a consequences of being "good" or "evil" by nature. And everyone bears responsibility for their own actions and is accountable for them.
I'm always baffled by the belief that some people have, that understanding what evil people are about makes it impossible to denounce or fight evil. I would say that it's exactly the opposite. Sure, it is much more comfortable, and it feels so much safer to believe that people who do evil things are some sort of alien monsters who have nothing in common with us nice folks. But that attitude only blinds you to see the roots of evil and notice it developing. If you look better, you can see seeds of evil in your neighbors and relatives and co-workers and all those nice and normal people. I've heard nice and normal people say things that Hitler would've been proud of. It may be disturbing to think how many of those nice people could become Hitler or Goering or Eichmann under right circumstances, just like Hitler might have ended up being just another loser WW1 veteran and failed painter and Eichmann could have been just another nondescript clerk.
But such views are really disappointing from a writer. I expect from true art to be provocative and challenging and not afraid to explore the roots of evil, rather than to be offer safe and simple conclusions and to imply that evil is something that has nothing to do with us, something that it's impossible to relate to.
(And let's not get into how borderline unprofessional I think it is for a producer/showrunner to start a one-sided public debate with an actor, with none of the alleged arguments from the other side available in their original form.
Although probably not as unprofessional as it is for certain interviewers to keep repeating quotes from Behr's interview about what Alaimo was supposed to have thought, according to Behr [which I would take with a grain of salt, as people usually tend to exaggerate and misunderstand the views of people they disagree with...], and state them as facts; i.e. if you're going to start a question to every ex-DS9 cast member who currently plays a villain with: "Are you like Marc Alaimo, who believed that Dukat was the real hero of the show..."., how about first checking if there is any interview with Alaimo, any convention report, anything with a direct quote where he actually stated that or something like that? Hint: to the best of my knowledge, there is no such thing.)
Incidentally, Ron Moore's comments on Dukat tend to sound more reasonable than Behr's - and I think he hits the nail on its head here (
http://memory-alpha.org/wiki/Dukat):
"
I don't think of him as being completely evil through and through to the point where every thought, every impulse is shaded by a nefarious agenda or horrid motive. We've seen other aspects to this guy over the years. He can
be charming. He can
be generous. He can
do the right thing. All of that somehow makes his "evil" actions all the more despicable, because we know that there was the potential in there for him to be a better person. But sometimes the clichés are true: Hitler loved his dog. No human being (and by extension, no Cardassian) is one hundred percent pure evil. But there is a "critical mass", if you will, where the dark deeds attributed to one person become so overwhelming that they swamp all the redeeming characteristics. Dukat is a bad guy. A very bad guy. He has a lot of blood on his hands and it's hard to see how his smile and innate charm can wipe that clean." (
