And because of that, I thought Dukat was wasted as a character. I honestly thought that the bastard would've been a great anti-hero. Where over the years he would've gone through a "redeeming" where he would've helped the Federation but still be the seriously flawed, megalomaniac man he always was.I think that's a reason why Dukat was such a great character. He was more than just one-dimensional character, and — just like normal people — had many facets of his personality.
Besides, Dukat as a Freedom Fighter against Dominion occupied Cardassia would've been a nice symmetry with Kira and Bajor.
