I think the Joker actually loves Harley but doesn't really understand that feeling so he tries to kill her...

Both.

I think he really does love her, he's just so far gone that he's completely forgotten how to express positive emotions

I can't see how he loves her. Or maybe like a convinient little pet.

And also people believing he is IN LOVE with her. How could he be in love with her when the 1# most important person in his whole life has been and always will be Batman? Joker loves Batman duh. He doesn't have time and capacity for Harley. Also he rarely thinks about her.

Joker try to kill her because he start to love her !!! He only can love Batman :P

@desiderina_redhead: PhycoPaths are not soulless. In fact quite emotionally sensitive. The fact of confusing and conflicting thoughts make Phycos "act out" In jokers case he has become so use to being an outsider. And the idea that someone would die for. Goes against everything he knew or thought he knew. He's instint is to kill Harley because she clashes with his thoughts on the world and that's the whole reason he is why he is. PhycoPaths can love. But generally find it contradicts what they thought. Phyopaths don't kill for the sake of kill. They have trouble processing their emotions(:

The joker actually does love Harley, and as a result tries to kill her because he hates feeling emotional for others, but he does use her for his dirty work. New 52 Harley Quinn is independent on the other hand and is no longer manipulated by joker.

@phycolove: @nkrinock: He used her , you think a guys like him could LoVE somoene lol, read the comics see what he has done.And Joker unlike an other genicidal Maniac Batman faces he has no clear or motive he just does without reason or meaningless ness of life. You think he would care about some girl?

Okay, I'm not too good with these things. But I think he loves her in his own way. He may seem bat sh*t crazy, but remember that he is insane. He abuses her, yes, he cares for her in his own way, very. He may abuse her, but like I said he's crazy, so he tries to show his affection. He basically has lead her on, but throughout the years, he would've killed her by now. But what's stopping him is how close he is to her now. He truly loves her in the inside, but just can't show it. He's stuck in that one place of insanity and trying to kill his only ever worst victim, Batman.

No. She's just his favorite toy. He's not capable of love.

The only person Joker really cares about is Batman. No sarcasm.

I wouldn't say care. I would say obsessed. I know it might sound like semantics but there is a difference.

@dernman: That is correct.

Personally I think he couldn't care less about her. He throws her life around like its a toy, but I do think he needs her in the sense to stand in for him when it puts him in danger, or when he needs to be somewhere but he also has another part of his plan to sort

Well Joker is a psychopath meaning he doesn't feel empathy. So I doubt he really loves Harley. And he definitely does use her.

It depends on the writer
