Well Joker is in a sense sane. Plenty of psychopaths are quite sane like many Gotham villains lol. She's as theatrical as they are though and would add to Gotham's ridiculous criminals. A better way to put it she hasn't started killing a lot of people.

She's really never going to start killing people. She hasn't so far, even though she's caused injuries. She's kind of like how a lot of heroes won't kill people, except villainous. Since she does kind of cause mass property damage and injure people. It kind of plays into how she's a performance criminal, though it's not just because she doesn't want to kill her audience like she says.
