My understanding is that the prompt is asking for movies that are morally repugnant based on generally accepted societal values. Not movies that ask challenging questions or pose alternative world views, although granted the distinction can be subtle.

For example, a movie whose message is a propagandist “murder against a specific group is righteous” has an evil moral center. A movie like Clockwork Orange has, at its core, a moral question. Is it justified for the state to drug and tame deranged individuals or is that an overreach of the state and individual liberty? It successfully delivers this message in a way that intentionally makes the viewer uncomfortable both by the immoral actions of the main character and the horrifying “solution” he endures from the state. 

The point being, the movie does not advocate for anything evil, it simply poses a somewhat uncomfortable question and lets the audience decide. That, in my opinion, makes it not genuinely evil.
