Chaotic evil

She cares only for herself with a complete disregard for all law and order and for the welfare and freedom of others. She will harm others out of anger or just for fun. She can/will be mindful of her companion but don't think you rule her, you will find yourself on the business end of her anger. She usually operates alone because she does not work well with others. she can be controlled but only temporarily. which is why she comes with a keeper. 

They are driven by their desire to spread Chaos and Evil because they enjoy it. She is unpredictable and freely expresses wild and intense emotions because she sees no reason to control or suppress them. Chaotic Evil characters are the most Evil of all because they are out to destroy everything – order, tradition, life, freedom, and choice.
