How is Daisy a victimizer throughout the novel and whom does she victimize?

Daisy is ready to use and abuse everyone that meets her
and anyone that she can.  In some ways she is even a victim of her own disconnection
from reality.  Likely one of the first people she victimizes, in a way, is her husband
Tom, but that is a two way street since he is cheating on her at every opportunity. 
Since their relationship is a bust, she just uses him for the position and power his
money provides, as well as the general illusion she has about money making everything
ok.

The greatest victim (though also a victim of his own
illusion) she preys on is Gatsby himself whom she leads on only to destroy him when she
realizes that he could be the vehicle for saving her from her murder (or manslaughter). 
He is destroyed and despite that fact continues to long for her.
