The DS9 writers and actors also had workarounds for Berman. They would write a scene and then a close but Berman friendly version. He would ok it and then the actors would “improvise” the original script.

Dukat was another case of the writers and actor colluding. Berman wanted him to be straight up evil. The writers and actor wanted to give him respectable motivations for his evil acts.

So he is not a good guy but you can respect the love for family and state that drives his terrible crimes.
