Harley Quinn is often depicted in the comics and the Batman animated series(there is multiple versions) as a psychologist who fell in love with Joker went insane and became his crazy side kick. She is often not depicted in any of the batman films. Which is disappointing and I think it would be nice to add her to the films. She was niave and states that joker "Brought fun into her life and listens to her issues for once". This would indicate she felt ignored and bored. Many women actually fall in love with killers/crazys all the time. "Charlie manson" has a bunch of women outside prison sending him letters and so did/do a lot of other criminals that seem to be pure evil. When she becomes Harley Quinn she adds a Boston accent which she previously did not have, adopted this cute little girl persona and started giving people cute little nicknames. A complete 180 from her previous personality. So what is wrong with Harley? Why did she become so obsessed with Harley? Was she feeling neglected and so clinged to someone that made her feel important? We all know that the joker is manipulative but not one trusts the joker. Even Batman sees though his lies. So why? What is the psychology of Harley? What issues made her fall in love with joker?
