Waltz, and the other Dukat stuff that follows, is influenced by the decision in the writing room to make it as clear as possible that Dukat was evil, because they were worried that fans were finding him too charming and defending him online. It has some compelling moments, but it's also ham-fisted and the beginning of the deliberate attempt to depict the character in a way that feels far too forced and silly. Yes, he absolutely committed disgusting actions, but there are ways to show this without turning him into something as flat and boring as they did here.
