You've seen a billion images of her by now, probably. That girl, a fictional female that women are loving, even my own female coworkers at work. She is a too perfect example of the degradation of women in the USA today... While not a majority, it is all too common to see women like Harleen in real life. To see normal women admire her and want to dress up as her is... well, disgusting.
1. She had a bright future, once.
Harleen, as far as we know, was a woman with a decent life. Apparently single, but she had a doctorate in psychology and was making huge career progress working in criminal psychology. Not perfect, but if you're an attractive, happy person making strides in a respectable career field, that's hardly nothing. She still could have married and had a happy life. Perhaps a few kids, a nice apartment or home, had a loving husband. When she was older, she would have likely had grand children, an extended family to spend her days with, a legacy. Like too many real life women, she had a bright future and could have chosen to have a good life.
2. Then threw it away.
Harleen could have married a good man and had a good life. What did she instead decide to do? Throw it away because she "fell in love" with a psychotic mass murderer. Like too many real life women who literally decide to date thugs, criminals, and garbage. And just like too many real life cases, he is also abusive to her--evil men don
See a real life example--a 36 year old corrections officer, left her husband for a 21 year old inmate, and then hanged herself after he robbed her and humiliated her.
3. Harley Quinn--a Corruption
Simply put, what is Harley Quinn? She is a corruption of what should have been good. She's a slut, a criminal, sleeping with an evil criminal. What could have been a good life, now set on a path that only ends in depression and grief and ruin. Even worse, she somehow has become an idolized character for far too many girls, when characters like her should be viewed as horrendous and ruinous, anathema. We as a society should idealize the proper sort of women, not the ruin that is far too common in real life.
