I have seen all over the internet cases of people saying, “I need a relationship like Harley Quinn and the Joker” and then they use some sort of ridiculous emoji of some sort.
No. You don’t.
A recent photo released from the set of the Suicide Squad shows this as well.
The movie cut down the dynamic of the relationship to make it seem significantly less abusive than it actually is, but the photo hints that they filmed a lot more, probably showcasing the horribly abusive nature of the evil duo’s love.
The relationship between the Joker and Harley Quinn is famously abusive, significantly more so in the comics than anywhere else; and no, it isn’t just mentally and emotionally abusive, the Joker has been known to physically abuse his psychiatrist-turned-lover.
There is definitely a point where love goes too far and becomes obsession, and Harley is far, far beyond that point with her “Puddin'”.
So no, teenaged girls, you do not want a relationship like the Joker and Harley.
