"I can see that I make everybody uncomfortable."

 Jenny knew she made people uncomfortable and she didn't feel like she fit in.  She was wicked, but maybe the writers decided she still possessed some inner wisdom combined with twisted half truths.  

 Jenny, the character, reacted to life in a very personal way.  Who does life to perfection anyway?  Mia Kushner did a fabulous job convincing us that this character actually lived and breathed. 

There was an enormous  amount of real, true, seething audience animosity for this character.  To the degree that someone could despise that character's flawed traits, this exposes one's separation from that which they may see in themselves.
