Harley to me is a symbol of strength and ferocity. She shows 1. There's alittle bit (or a whole lot) of crazy inside each of us, just depends on who you are today. And 2. She thrives in the chaos and abuse. Her character has been beaten, attempted murder, shunned, and all out abused....but she's still a strong independent character that desires affection and love, no matter what form
