Harvey Dent (Batman: Gotham by Gaslight)

"You never slow down, do you? As soon as one lover boy's unavailable, you're on to the next chump. I can't imagine what I ever saw in a whore like you"

- Dent's (hypocritical) condemnation of Selina Kyle Harvey Dent is a secondary antagonist in the animated movie ''Batman: Gotham by Gaslight. ''He is introduced as Bruce Wayne's "oldest school chum", and a prosecuting attorney for Gotham City. However, he is also shown to be a misogynistic, self-centered man who betrays Bruce later by having him scapegoated as Jack the Ripper.

He is voiced by Yuri Lowenthal.

history
Harvey Dent first appears at the Gotham World's Fair to bear witness to it's opening. He tries to shut Selina Kyle down when she protests that the police are doing nothing to protect the women of Gotham City from the serial killer butchering them. Later, he and Bruce Wayne tour the town together, where it is revealed that Dent is courting Selina Kyle, intending to make her his mistress despite the fact that he is married (also brushing off Bruce pointing this out). It becomes apparent that he barely cares about what Jack the Ripper is doing to the women of Gotham City, caring only about himself and his personal pleasures.

Later, when Jack the Ripper murders a woman who earlier accosted Bruce Wayne and tried to extort money from him, Dent sells his out his old friend to the police and remorselessly (even gleefully) has him prosecuted as Jack the Ripper, jailing him with no regard for their past friendship and by all appearances enjoying getting rid of Bruce (possibly so he can have Selina Kyle all to himself). Later, when Selina goes looking for James Gordon, she runs into Harvey Dent again, who sneers that she just goes from one man to the next, deriding her as a whore and openly wondering what he ever saw in her. Dent is not seen again after this.

trivia

 * The premise of Harvey Dent having an unrequited attraction to Selina Kyle was also explored in Batman: The Telltale Series.
 * This version of Dent is in some ways worse than both his portrayal in the original Gotham by Gaslight comic (where he only prosecutes Wayne after he's been arrested and framed rather than deliberately selling him out and enjoying his downfall, and is also not openly misogynistic), and the more conventional portrayals of the character (who have a tragic backstory and honorable qualities, things this Harvey Dent completely lacks).
