>>100032456Not OP, but in the stories where I enjoyed the Joker's portrayal the most, he usually pulled off some kind of surprise moves that I wasn't expecting at all. I think the most important part about his character is that he needs to be written as a very unpredictable character who's operating under fuzzy logic, and that it should be difficult to predict what he's about to do next.
Also, since audiences today are very aware that he's a lethal guy who kills people for a punchline, I prefer stories where he defies that reader expectation and doesn't actually kill anyone. An unexpected act of kindness from an established villain can mess with one's mind, and I think these types of mind games can make the character's next moves even more difficult to predict.
Keeping his death toll lower would be better for Batman's character, too. Every time the Joker commits mass murder or causes personal losses to Bruce, it makes the readers ask that old question about why can't Batman just kill him.
